Abstract

A fully integrated voltage-controlled oscillator (VCO) working in K-band with a large tuning range and a low phase noise fabricated in a 0.18 μm SiGe BiCMOS technology is presented. To achieve a wide tuning range while keeping a low VCO tuning sensitivity (K_VCO), the coupled LC tanks are used. The VCO achieves figures of merit (FOMs) greater than -180 dBc/Hz for both phase noise and tuning range with power consumption of 7 mW.
