    abstract = {In this paper, a functional principle for a broadband thermal detector suited for a monolithical integration is shown. Two tantalum load resistors are heated by an input signal, while the temperature at a fixed distance is recorded on chip with a differential temperature sensing bridge. An integrated differential to single-ended stage amplifies the bridges differential voltage and makes an output voltage proportional to the input power of the detector available. The thermal resistance and capacitance between the load resistor and the sensing cell act as a low pass filter in the electrical regime. Based on this concept, a detector chip has been designed, which has been analyzed in thermal simulations. The realized detector has been characterized on-chip and bonded to a microwave substrate for a system performance estimation. Its input impedance is tuned to 50 Ohms and measured matching is better than -15dB from 10MHz to 43.5GHz. With a low supply voltage of 1.5V and its active area of around 80x36um2, the detector is suitable for an integrated power measurement solution.},

    @inproceedings{girg2016a,
    abstract = {With increasing data rates in communication systems, the call for wideband transceiver solutions capable of processing complex modulation schemes is getting stronger. Unfortunately, this goes along with power hungry systems and more complex integrated circuits. A novel receiver architecture, which addresses these issues, is based on the simultaneous phase and amplitude regenerative sampling system. Its system exploits switched injection-locked oscillators and their capability to regenerate signals with a gain of over 40dB. This paper demonstrates an integrated solution for phase demodulation in such an architecture. The proposed concept uses the low complex but efficient self-mixing principle and consists mainly of double-balanced Gilbert mixers, amplifiers, a delay line and passive power dividers. The detection of the phase is achieved through self-mixing the regenerated signal with one path delayed by a symbol period. The architecture achieves 2 GBaud/s with 8 th order differential phase shift keying at a frequency of 60 GHz and is realized in a 130nm SiGe BiCMOS technology.},

Therefore, a highly integrated two-port VNA with a multioctave bandwidth from 4 to 32 GHz is presented. The proposed system is based on a fully integrated radio-frequency frontend consisting of a two-port stimulus, a four-channel heterodyne receiver, and a wideband testset. The testset is comprised of on-chip multisection directional couplers. The chip is operated inside a hardware demonstrator using a 16-term calibration procedure. The measurement of arbitrary devices under test is in excellent agreement with commercial measurement equipment and showed a mean deviation from the reference measurement of 0.17 dB and 1.29° regarding the forward transmission of a coaxial 30-dB attenuator. The system and receiver dynamic ranges are 44-77 and 82-101 dB at a resolution bandwidth of 100 kHz over the full system bandwidth. The measurements are highly repeatable and are robust against drift over time. As a proof of concept, the developed integrated network analyzers are utilized in a biomedical sensing scenario with an external and an on-chip sensor. Both approaches showed good sensitivity regarding the mixture ratio of binary solutions of ethanol and methanol.},

Insbesondere hier ist eine Überwachung des menschlichen Wasserhaushaltes wichtig. Ein neuer Ansatz schafft die Möglichkeit, Nutzern auch im Alltag die aktive Überwachung ihres Hydratationszustandes zu ermöglichen. Das Verfahren beruht auf Sensorik, die als Stimulus eine elektromagnetische Welle verwendet. Aus der vom Gewebe reflektierten Welle können Rückschlüsse auf die Wasserkonzentration gezogen werden. So wird ein alltagstaugliches und hochintegriertes Detektionssystem möglich, welches vom Nutzer permanent getragen werden kann und die Analyse des Wasserhaushaltes erlaubt.},

    abstract = {An integrated analog frequency multiplier for a novel high data rate communication system has been developed to multiply a 18 GHz input signal by ten to generate a 180 GHz output signal. With a first step the 18 GHz input signal is fed into a times five edge combiner, which generates an intermediate frequency of 90 GHz. Therefore five different phases with a delta of 72 degree are needed, that are provided by an active allpass filter chain. In a second step the 90 GHz intermediate frequency is given into a double-balanced Gilbert cell mixer. Here, frequency doubling is achieved by feeding the same signal into the LO and RF port of the mixer. Hence, the overall output frequency of 180 GHz results in 180 GHz with a simulated output power of -7 dBm. All simulations are done post-layout. The chip is implemented in a 130 nm BiCMOS technology with a chip area of 0.9 mm x 1 mm.},

In contrast to the conventional measurement approach using two measurement antennas, the proposed measurement setup uses only one antenna and one metallic reflector. Measurements have been performed using a patch antenna immersed in a steel basin filled with a tissue-equivalent liquid. The microstrip antenna has been optimized for an application in the 2.45GHz ISM band and features a biocompatible passivation layer and a rigid aluminum housing. The tissue-equivalent liquid mimicks dielectric tissue properties over a hypotonic hydration change. The steel basin acts as a liquid retainer and as a metallic reflector for the measurement setup. Measurements with the proposed setup have shown, that a clear distinction of physiologically relevant hydration levels is possible.},

The first design example is a broadband low-power active balun, employing one of the presented feedback techniques. It is capable of operating with a gain of 2.2 dB and BW of more than 70 GHz. The amplitude imbalance is less than 2.4 dB, while the phase imbalance is below 7 ° up to 60 GHz and 14 ° up to 70 GHz, consuming a low-power of 29.7 mW. The second design example is a differential three-stage amplifier, incorporating the two techniques, where their combined performance achieves a gain of 54 dB and a 3-dB BW of 25 GHz, resulting in a gain-BW product (GBP) of 12.5 THz, with a power consumption of 180 mW from a 3.3-V supply.

The reflectometric architecture used herein allows a frequency independent q-point configuration of the sixport by implementing microstrip linelength compensation. Broadband matching of around -10 dB could be reached at all ports in a frequency range from 1 to 30 GHz. Acceptable coupling from DUT port to measurement output could be reached in a range from 2 to 29 GHz. Frequency compensation of the structure and an optimal q-point constellation of 120-120-120 have been verified by measurement. Due to its broadband functionality, compactness and cost efficiency, the proposed system is suitable for a wide range of microwave measurement applications.},

The PRBS generator consists of two parallel complementary rows of linear feedback shift registers (LFSR), operating up to 40Gb/s, where the generated PRBS from each are multiplexed to provide a bit-rate of double the clock frequency, reaching up to 80Gb/s. The clock distribution network was carefully optimized for a reduced amplitude and phase error to push the boundaries of the maximum achievable bit-rate. The PRBS generator is capable of generating bit-rates ranging from 10Gb/s up to 80Gb/s, with a power consumption of 576 mW to 1 W.

    abstract = {This work presents a highly integrated transmitter (TX) and receiver (RX) chipset operating from 50 to 100 GHz. The local oscillator (LO) is realized using a high output power millimeter-wave integrated frequency synthesizer with an octave output frequency range. The proposed low-complexity discrete tuned synthesizer architecture employs a single wide-tuning range voltage-controlled oscillator core and a single-sideband mixer, which can be switched to operate as a LO amplifier. An ultra broadband variable gain amplifier, with a gain control range $>{hbox {25 dB}}$, is used at the output of the synthesizer to provide a tunable output power. A maximum output power from $+{hbox{7}}$ to $+{hbox{12 dBm}}$ and an output phase noise from $-{hbox{83}}$ to $-{hbox{96 dBc/Hz}}$ at 1-MHz offset are measured over the complete output frequency range. Moreover, a spurious suppression $>{hbox {22 dB}}$ is achieved over the entire synthesizer's tuning range. The RX shows a conversion gain $>{hbox {19 dB}}$ and a noise figure $< {hbox {9.5 dB}}$ from 50 to 100 GHz. The TX's measured saturated output power is from $ +{hbox{6}}$ to $-{hbox{1 dBm}}$ over the entire frequency range. The complete chipset is realized in a commercial low-cost SiGe:C technology with an $f- {t}/f_{max}$ of ${hbox{170/250 GHz}}$. Each of the TX and RX chips including the frequency synthesizers draw a current of 370 mA from a 3.3-V supply.},

An array of four crosscoupled voltage controlled oscillators with subsequent frequency ranges is implemented. The oscillator cores only draw 13mA from a 3.3V supply. Another 13mA is drawn by following buffer stages. A 4-to-1 multiplexing amplifier acts as a combiner providing the octave-wide bandwidth at a single differential output. The output power was measured to be between -2.5 dBm and 0.7 dBm. The signal source provides a good phase noise performance of -105 dBc/Hz at 15GHz and -96.8 dBc/Hz at 30GHz at an offset of 100MHz from the carrier frequencies.

    abstract = {Sudden cardiac arrest (SCA) is one of the leading causes of death worldwide. Studies have shown that roughly 90% of all patients suffering from SCAs die due to ventricular fibrillation. This phenomenon is best described as an electrical chaos in the myocardium leading to fast but at the same time very short movements of the muscle. This results in a total collapse of the blood circulation and after 3–5 min, the death of gray matter. Without any external help, this will lead to death. In the United States, for instance, 325,000 people are affected each year. It is indisputable that the quality of a cardiopulmonary resuscitation (CPR) can make the difference between life and death. In 2010, the European Resuscitation Council (ERC) as well as the American Heart Association (AHA) submitted official guidelines for resuscitation. According to the ERC and further research results, the basilife support can be significantly improved by a feedback system. The recommendation for CPR feedback systems has subsequently been adopted by the German Medical Association (GMA). A CPR feedback system gives a response to the first aider about the quality of the resuscitation (compression depth and rate).},

    abstract = {Introduction This paper presents a scalable, flexible and energy efficient embedded communication platform for seamless data transfer of medical sensor signals from the sensor acquisition point to a medical service centre. The presented platform can be used as an assistance system for improved medical support and care of patients and lifestyle users by providing vital parameter data to the service centre for a variety of individual assistance services. Methods The presented hardware platform is comprised of two functional blocks. A sensor platform has been implemented containing a medical device controller for collection of the data of various medical sensors connected via an analog front end or by an integrated Bluetooth transceiver module. Furthermore, a communication module including an A-GPS receiver enables GSM and UMTS data and voice connections to a central infrastructure and provides positioning data of the patient current location. The software protocol stack for the sensor data transmission is kept flexible in order to allow different communication standards. Special emphasis has been put on the energy management concept to optimize the battery life time and increase patient acceptance. Results The modular hardware and software co-design allows the connection of a wide range of different medical sensors, adjusted to the patient needs and specific use case. The use of data reduction and pre-processing techniques allows a reduction of the amount of data transferred to the infrastructure. Additionally, the centralized aggregation of sensor data enables short transmission times. This, in conjunction with an application specific energy management concept, leads to an increased battery life time. Conclusion The presented platform allows the collection of vital parameters from a variety of medical sensors for personal assistance of patients and elderly people. This concept allows new possibilities in diagnosis and treatment with the goal of an increased quality of life through the extension of independent at-home living periods.},

Cascading multiple quarter-wavelength line segments leads to an increase of coupling bandwidth up to 180% but also results in discontinuities of geometry and thus in strong reflec- tions. Furthermore, the isolation is diminished. To avoid these effects a design technique for the generation of continous, non-uniform geometries is analyzed and implemented. Two methods for the coupler synthesis are proposed and compared. One is an approximational approach and uses two sets of equations. The other uses accurate 2D field simulation of the propagating modes and is universally applicable to any kind of coupled transmission lines. The completely synthesized couplers are simulated in CST Microwave Studio and achieve very good results for coupling, isolation and return loss. A nominal -10dB wideband coupler at a center frequency of 15GHz and a nominal bandwidth of 164% is built in a multilayer stackup. Good agreement between measurement and simulation results is observed.},

    abstract = {Modern wireless sensing and communication systems are often based on high bandwidth and high carrier frequencies. In the range beyond 100 GHz, common receiver architectures, like active homodyne or heterodyne receivers, have an issue with the amplification needed for mixing. Also, high bandwidth is a problem for these systems. In this context, the six-port receiver is a good alternative, just as well as for lowvolume markets. The six-port concept is based on the additive superposition of the two RF input signals using four different relative phases leading to constructive or destructive interaction. The resulting signals are directly downconverted to baseband by diode circuits operated in detector or mixing mode. The complexvalued information can be easily reconstructed from the four baseband voltages. Historic evolution leads from the reflectometer approach for an alternative vector network analyzer to receivers for sensing and communications. A recent topic is the technology gap in automotive workshops for adjusting the long-range radar sensor of a car. Here, the six-port concept as alignment tool is a good choice, because of its excellent phase resolution. Currently, the integration of the six-port receiver on a MMIC for frequencies beyond 100 GHz is the focus of current work and will be intensified in the future. Will the six-port concept replace common active homodyne and heterodyne receivers? No, but it is a serious alternative for millimeter-wave frequencies and ultrahigh-bandwidth applications in wireless sensing and communication systems. This modern concept can tap new markets for both wireless sensors and sensor networks.},

To reduce computing time the whole signal flow is processed in a complex baseband representation and scattering center models are used as substitute for complex polygon targets as further improvement. Nevertheless all effects occurring at harmonic bands and at DC due to nonlinearities in the transmitter and receiver circuits are well reflected in the simulation. A typical road scenario is simulated and the results show the capabilities of the simulation technique in terms of speed and accuracy.},

    abstract = {Silicon-based technologies have enabled the monolithic integration of transceiver circuits with operational frequencies up into the millimeter-wave regime. While high integration relaxes the requirements on RF chip-to-chip interconnects and external circuitry, it imposes serious challenges upon the traceability of failure mechanisms and functional errors of the individual building blocks that comprise the front-end. Additionally, expensive external measurement equipment in combination with complex, error-prone, and time-consuming calibration procedures, necessitates the development of on-chip test modules. It has been shown that a variety of built-in test schemes are currently the topic of research for both the mixed-signal and microwave domain. Solutions for the individual building blocks that will enable direct verification of performance parameters have been presented throughout this article. Current RF transceiver architectures will require a mixture of both paradigms for successful implementation of integrated test strategies. It is the authors' belief that the application of such concepts is a must for future integrated transceiver systems to meet the stringent requirements of time-to-market and low-cost of mass market consumer products.},
