Abstract
A wide tuning range 24GHz VCO (voltage-controlled oscillator) using IBM 90nm CMOS process is presented. Switched inductor and two bits capacitance array offer a widely tuning range. In addition, optimized switches are adopted to improve both tuning range and phase noise performance. Simulation shows that -101dBc/Hz phase noise is achieved at 1MHz offset. The tuning range of the VCO spans from 21.9GHz to 27.1GHz. Total power consumption of the VCO core is 3.3mW from 0.8V supply.
