CMOS millimeter-wave signal sources and detectors

Abstract

The feasibility of CMOS circuits operating at frequencies near 200 GHz has been demonstrated. A 140-GHz fundamental mode VCO in 90-nm CMOS, a 192-GHz push-push VCO in 130-nm CMOS, and a 180-GHz detector circuit in 130-nm CMOS have been demonstrated. The VCO circuits exhibit the highest fundamental and harmonic operating frequencies ever achieved by silicon integrated circuit technology. © 2007 IEEE.
