Abstract

The VCO circuit is widely applied in various communication circuits. This paper describes a low power ring voltage control oscillator. The VCO consists of five stages, and each stage uses differential structure. The VCO is the single-ended output. The chip is fabricated in 0.18μm CMOS technology of TSMC in Taiwan. The chip core area is 0.25mm × 0.05mm. Measurements show that the power consumption is about 9.2mW at a supply voltage of 1.75V. The center frequency is 62MHz. The phase noise is -89.39dBc/Hz@1MHz. The VCO can be used in PLL of the GPS RF receiver.
