Abstract
In this paper, a low power and high noise immunity VCO is proposed and analyzed. The novel voltage controlled oscillator (VCO) is proposed to reduce the total power consumption for half-digital phase locked loop (HDPLL) application. By HSPICE simulation results, the power dissipation of the low-power VCO can be reduced over 50% in comparison to conventional VCO. Moreover, the novel VCO also have good immunity in noises. For example, the new VCO have low jitter and low power-supply noise. Thus, the novel VCO can be used in the high performance HDPLL.
