Abstract

This paper presents a 60 GHz voltage controlled oscillator implemented in conventional 65 nm CMOS technology. This VCO employs an alternative tuning system based on the Miller capacitance instead of conventional varactors. The presented VCO has a tuning range of 10.5 % and operates in the frequency range of 59.5 GHz to 66.1 GHz. It has an output power of -13 dBm and a phase noise of 80 dBc to -85 dBc/Hz @ 1 MHz over its entire range. The figure-of-merit (FOM) of this VCO is -162 dB.
