    abstract = {This paper presents a highly efficient 3-stage differential Class-B power amplifier (PA) for short range radar applications, realized in a 28nm bulk CMOS technology. Measurement results show a saturated output power (Psat) of 11.9dBm with a 20.7% power-added efficiency (PAE) at 60 GHz. Moreover, the measurements show that for a frequency range from 57 GHz to 64 GHz, the Psat varies from 10.5dBm to 11.2dBm and the circuit draws 26mA from a 0.9V power supply. Furthermore, the fabricated chip has an area of 0.61mm x 0.31mm including the pads.

    @inproceedings{voelkel2019c,
    abstract = {In this paper a 60 GHz monolithic bistatic interferometric
    radar transceiver for high precision measuring is
    presented. The integrated transceiver has been designed using
    a 0.13μm SiGe BiCMOS process from IHP (SG13G2) and
    includes a LNA, a passive six-port structure, detectors, multiplier,
    multiplexer, power amplifier and a digital interface. The chip has
    a size of 2330μm x 1360μm and a maximum power consumption
    of 533mW from a 3.3V power supply. The circuit provides two
    frequency inputs of 7.5 and 15GHz and multiplies them up to
    60 GHz at a minimum input power of -20 dBm. The chip delivers
    a maximum output power of 9dBm at 61 GHz. The input path
    is selectable and the output power is adjustable by a digital
    interface between -23 and 9dBm at 60 GHz. Also the reference
    input power of the six-port and the RF input power can be
    adjusted in a range of 13.2 dB. The minimum input referred
    P1dB is -24.1 dBm. With a multiplexer, the receiver reference can
    be separated from the transmitter, which allows the use of both
    independently from each other. The serial interface is realized
    in 0.13μm CMOS logic and consists of a 20 bit shift register,
    decoder and an analog interface.

    @inproceedings{ahmed2018,
    abstract = {In this paper, we investigate two types of data transmission in human body communication (HBC) with galvanic coupling: Intra-body communication along a human arm and inter-body communication between
    two arms in touch. For the former, the effect of bending the arm is investigated, too. The arms were modeled
    as five-layers concentric cylinders of different types of tissue. For simulation, the finite element method (FEM) COMSOL Multiphysics5.3a software was used. The influence of different HBC key parameters including applied frequency, distance between transmitter (TX) and receiver (RX), bending, contact area between the contiguous models, and induced current were investigated. The results show that the transmission loss increases with the increase of the transmission length and operating frequency. The electrical potential is directly proportional to the induced current. Bending helps to improve the detected signal in the cases of short distance between TX and RX around the curvature. For distant transceivers, both straight and bended models tend to behave in a close manner. However, no joints are added to the model. The signal degradation in inter-body communication is considerably higher compared to intra-body communication at the same horizontal distance between TX and RX. At frequencies above 200 kHz, both inter-body and intra-body communication give close values when the contact area between the arms covers the distance between TX and RX electrodes. In addition, by increasing the contact area and avoiding gaps between the models, the detected signal is improved. The results illustrate the main determinants of information transmission between both sensors within a body-sensors-network and between different person.

    abstract = {This paper presents several improvements of the energy-eattern based sequence detection (EPSD) algorithm for FSK-based single-phase power line communication (PLC) systems, in terms of complexity, reliability and synchronization. A time synchronization is presented which fulfills the well known task of synchronizing transmitter and receiver, but also helps to avoid transmissions in periods of rough noise conditions. The synchronization method is based on a maximum-likelihood approach that makes use of the phase of the mains voltage. Further improvements concern the codes used for the transmitted sequences as well as the combination of the information within both FSK carrier-frequencies in terms of equal gain and maximum ratio combining. Additionally an approach for a lowcomplexity frame synchronization is presented.

    @inproceedings{jakob2019,
    abstract = {Transitions for planar transmission lines on printed circuit boards (PCB) to rectangular waveguide are challenging to design and manufacture. This paper introduces two transitions, the first one is a broadband transition from WR12 (60–90 GHz) waveguide to a stripline (SL) and the second is a narrowband transition to a grounded coplanar waveguide (GCPW). The focus at the first transition is based on the fact that signals can be transmitted in the complete EBand. In the process, many manufacturing possibilities were exploited. For the second transition, the focus was on manufacturability in order to achieve the most cost effective transition possible. Design, simulated and measured results will be presented.

Here, the imbalance of contact impedance is investigated for different types of electrodes with capacitive coupling in terms of static imbalance as well as dynamic variation during body movement. Flexible and incompressible materials like conductive foam and fabric showed the best overall performance. The negative effect of rigidity can partly be compensated by adding conducting foam, while soft materials can profit from an increase of electrode area.

The system consisted of two GaN HEMT Doherty power amplifiers and a coupler to control the crosstalk between the two PAs. The team implemented a cascaded polynomial model that reduced unwanted static and dynamic effects as well as crosstalk between the two PAs, optimizing the overall performance of the system.
