Frontend Integrated Circuits and Systems

In the “Frontend Integrated Circuits and Systems” Research Unit we explore AD and DA converters, RF- and Mixed Signal-IP as well as frontend integrated circuits in communication and sensor systems. The team provides a solid background in data converters design, and integrated sensing solutions for a variety of applications such as LiDAR, thermal and ultrasound imaging. Moreover, we are focusing on RF- and MS-design, designing of ASIC, AFE circuits and FPGA-based protype for digital intensive transceiver architectures and smart sensors with the co-design of RFIC (SoC), SiP and heterogenous integration technologies.

Research foci

  • SAR ADC, Sigma Delta ADC, flash and cyclic TDC in ASIC and FPGA
  • RF DAC
