A good-performance high-frequency Phase Locked

Loop using a ring oscillator is described. A Voltag e Controlled

Oscillator with automatic calibration of frequency fluctuated by

proce ss and tempe rature variations is propo sed. The VCO

adopts new multiple-pass loop to improve frequency with

unchangeable stages (phases). The circuit is implemented with

TSMC O. I8um standard CMOS technology and power supply is

1.8V. Cadence and Matlab tools are both used to present

credible transistor and behavior simulation results .
