    abstract = {A multi-octave receiver chain is presented for the use in a monolithic integrated vector network
    analyzer. The receiver exhibits a very wide frequency range of 1–32 GHz, where the
    gain meets the 3 dB-criterion. The differential receiver consists of an ultra-wideband low
    noise amplifier, an active mixer and an output buffer and exhibits a maximum conversion
    gain (CG) of 16.6 dB. The main design goal is a very flat CG over five octaves, which eases
    calibration of the monolithic integrated vector network analyzer. To realize variable gain
    functionality, without losing much input matching, an extended gain control circuit with
    additional feedback branch is shown. For the maximum gain level, a matching better
    than −10 dB is achieved between 1–28 GHz, and up to 30.5 GHz the matching is better
    than −8.4 dB. For both, the input matching and the gain of the LNA, the influence of
    the fabrication tolerances are investigated. A second gain control is implemented to improve
    isolation. The measured isolations between RF-to-LO and LO-to-RF are better than 30 dB
    and 60 dB, respectively. The LO-to-IF isolation is better than 35 dB. The noise figure of
    the broadband receiver is between 4.6 and 5.8 dB for 4–32 GHz and the output referred
    1-dB-compression-point varies from 0.1 to 4.3 dBm from 2–32 GHz. The receiver draws
    a current of max. 66 mA at 3.3 V.

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.},

    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.},

    abstract = {This paper addresses the miniaturization of microwave vector network analyzers (VNAs) and the future vision of the VNA on a chip. 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.},
