Design of a 60 GHz, 11.7% Tuning-Range Voltage-Controlled Oscillator in 65 nm CMOS Technology

摘要

This paper presents a 60 GHz voltage controlled oscillator (VCO) for the unlicensed 60 GHz wave applications, based on a 65 nm CMOS process. The post-simulation results shows 1.66 mW output power, -91 dBc/Hz phase noise at 1 MHz offset is realized, and the consumption of the VCO core is 13.1 mW under 1.5 V supply voltage at 60 GHz. The tuning rang of the VCO is from 56.4 GHz to 63.4 GHz; 0.016 mm(2) chip area is occupied, and the figure of merit (FOM) of this VCO is as high as -176.8 dBc/Hz.
