mm-Wave CMOS Colpitts VCO & Frequency divider for the 60GHz WPAN

Abstract

A mm-wave CMOS Colpitts VCO and Frequency divider for the 60GHz WPAN fabricated with the 90nm TSMC Process is presented. The VCO is composed of a NMOS transistor-pair as a core circuit and 3 bit capacitor array for enhancement of the oscillation bandwidth. A mm-wave frequency divider is designed based on CML divider driven by colpitts's high voltage swing… (More)
