摘要：This paper present a single stage CMOS Voltage controlled oscillator with a high oscillation frequency and low power consumption. The VCO is a single stage circuit has a low phase noise due to reduced noise sources. The VCO is intended to operate as a frequency synthesizer in a PLL to generate local oscillator frequency (LO) for an acquisition system, providing in-phase/Q-phase outputs. The performance of the proposed circuit is evaluate in spice simulation by using Tanner software, the VCO we use S-Edit, T-Spice, W-Edit in a 0.18-μm standard CMOS process. The results show that the oscillation frequency of VCO may vary between 0.58 to -2.79 GHz. Also, the phase noise performance of the VCO at oscillation frequency of 2.79 GHz is better than other. For the 1.8v supply voltage, the power consumption is 0.72 mW at the same oscillation frequency
