Abstract :
In this paper, the low power VCO is proposed and analyzed. A novel low power voltage controlled oscillator (VCO) is proposed to reduce the total power consumption of the Half-Digital Phase Locked Loop (HDPLL). By Hspice simulation results, the power-frequency ratio of low-power VCO can be reduced over 30% in comparison to conventional VCO. Thus, the novel low power VCO can be used in the low power HDPLL
