Radio-Frequency and Millimeter-Wave Integrated Circuits

Radio-frequency integrated circuits have made a profound impact on the lives of people around the world through the introduction of low-cost wireless communication and internet. As radio-frequency communication proliferates, new systems and circuits are require to operate over multiple standards and bands.

As RF bands become crowded, millimeter-wave bands offer new spectrum that promises much higher data rates. Millimeter-wave circuits and systems realized on silicon integrated circuits could open new markets for high-speed wireless communication, imaging, and radar sensors. Our group invents new circuits to push the performance of integrated circuits operating at RF and millimeter-wave bands. These inventions are demonstrated using low-cost silicon integrated circuit processes.
