Abstract

In this paper, a low power and low phase noise of CMOS voltage controlled oscillator (VCO) is presented. The proposed VCO is adopted transformer feedback with drain-gate connection and body-biasing of the transistor. The bandwidth of the frequency range is from 4.97 GHz to 5.76 GHz with a 18.3%. The phase noise of the proposed VCO is -116.4dBc/Hz at 1MHz offset frequency. In a standard 0.18 μm COMS process with a 0.5-V power supply. The core power consumption of the VCO is 2.2 mW.
