Abstract

This paper presents a Wide Tuning range, and Low Noise Voltage Controlled Oscillator (VCO) based on cross-coupled and colpitts structures. The advantages of this work provide a low-phase noise and robust start-up condition, leading to minimized the dc power. In addition, a new structure of the Capacitor Bank is used in this structure to achieve a wide range of frequency. The proposed circuit is simulated in 0. 18 μ m CMOS process. The designed VCO covers the frequency range of 21. 95 GHz to 24 GHz with a tuning range of 8. 9%. Simulation results show that the phase noise is-120. 5 dBc/Hz at 1MHz offset frequency for 23GHz carrier frequency. Also, power consumption of the VCO is 6. 34 mW under 1. 8 supply voltage, and the figure-of-merit is-191. 68 dBc/Hz.
