A 57–63 GHz quadrature VCO in CMOS 65 nm

A 60 GHz I-Q VCO covering the frequency range from 57.5 to 63.1 GHz is presented. It exhibits a phase noise of − 95.3 dBc/Hz at 1 MHz offset from a 57.5 GHz carrier. Fabricated in a 65 nm bulk CMOS process, the two VCO-cores consume 30 mA in total from a 1.2 V supply.
