Abstract

A 15 GHz voltage-controlled-oscillator (VCO) with coupled coplanar waveguide (CCPW) inductor for LC resonator is proposed in this work. Methods including optimization of varactors and CCPW are applied to minimize the supply voltage and current. The CCPW is fabricated with the second top metal layer to improve the quality factor and isolate noise from substrate. The VCO is implemented using IBM 90 nm CMOS technology. The measured operation frequency ranges from 14.62 GHz to 15.5 GHz, and the phase noise is -94.86 dBc/Hz at 1MHz offset from 15.5 GHz. The VCO core draws 9.13mA current from 1.5V power supply. The calculated FoM is 168.
