Research
Areas of Research
RF and mm-wave integrated circuit, High-sensitivity receivers, Beamforming
Our research areas of focus include various aspects of RF and mm-wave circuits and systems, mixed-signal circuits, and beamforming networks. We have demonstrated ultra-sensitive room-temperature low-noise amplifiers (LNAs), novel noise-parameter measurement systems, new types of analog-to-digital converts, and unique beamforming solutions. For more information please contact Dr. Belostotski.
Cryogenic circuits and measurement methods
This is a new area for us. With the development of quantum computing, there is renewed interest in cryogenically cooled circuits. We have a cryogenic probe station and noise-parameter measurement equipment. Our first few designs are either in fabrication or already undergoing measurements. More to come!
