Abstract

This paper presents a wide frequency range, low power dissipation CMOS voltage controlled ring oscillator based on three-stage differential current-steering amplifiers (CSA) cell. The frequency of oscillator has a highly linear relationship with voltage. The VCO circuit realized through 0.18 mum CMOS process parameter shows wide operating frequency from 1.624 GHz to 3.229 GHz. The simulation result shows that power dissipation is 1 mW with 1.8 V power supply voltage.
