Abstract :
The design of millimeter-wave CMOS voltage-controlled oscillators (VCOs) is reviewed. A low parasitic cross-coupled transistor layout is developed, and used to demonstrate a 140-GHz fundamental mode VCO in 90-nm CMOS and a 192-GHz push-push VCO in 130-nm CMOS. These are the circuits with the highest fundamental and harmonic operating frequencies achieved in silicon integrated circuits
