1V 4.8mW 42.6-45.6GHz CMOS Voltage Controlled Oscillator for IEEE 802.15.3c Wireless Communication System

Abstract

A 1V 4.8mW 42.6GHz-45.6GHz CMOS Voltage Controlled Oscillator (VCO) is designed for IEEE 802.15.3c mm-wave wireless communication system. The oscillator provides a center frequency of 44.1GHz and is implemented in 90nm Logic CMOS technology. The oscillator core consumes 4.8mW through 1.0V supply voltage and the active area is 0.05mm(2) only. A tuning range of 3.0GHz (42.6GHz-45.6GHz) with maximum control voltage of 1.0V can be achieved. And the phase noise is -93.7 dBc/Hz at 1MHz offset from the center frequency. The calculated figure-of-merit (FOM) is -180.1 dB.
