Abstract

This paper designed a new low phase noise voltage- controlled oscillator (VCO) with harmonic filtering resistor and source damping resistor. The author analyzed and modulated the results by the simulator of Mentor Graphics in a 0.35-um CMOS process, and achieved the optimization scheme in the end. The simulation result shows the VCO can reach a phase noise of - 124.9 dBc/Hz at 1 MHz offset while working at 4.6 GHz in a 3 mA excursion current. During the 0 to 3 controlled voltage the tuning range can reach 18.5%, and the power consumption is only 7.09 mW.
