Niknejad Research Team:
Integrated Circuits for Communication and Sensing
Our group conducts research on the design of CMOS/SiGe integrated circuits for wireless communication, sensing, imaging and radar from DC - sub-THz frequencies. We design RF, microwave, and mm-wave devices, circuits, and packaged systems. See our publications for detailed reports on our research. We perform our research at the Berkeley Wireless Research Center
