摘要：
In this paper, a new delay cell of the voltage-controlled oscillator (VCO) is proposed The new circuit is designed and fabricated in TSMC 0.25um 1p5m CMOS process with a 2.5 V supply voltage. It utilizes the skill that decreases the transient time to achieve the wider operating frequencies, lower phase noise and lower power supply noise. The structure of the VCO is implemented in the dual-delay path techniques. The simulation result of the operation frequency range is 0.85 similar to 2.1 GHz and the power consumption of the maximum oscillation frequency is 12 m W.
