摘要：This paper presents a simple architecture for Programmable Voltage Controlled Ring Oscillator (VCRO) on 3-stages ring topology in TSMC 0.18um CMOS technology. The output frequency range from 1.92 GHz to 2.84 GHz and centre frequency 2.49 GHz is achievied with input digital bits range from “000” to “111”. The power dissipation is 0.31mW @2.84GHz maximum frequency. The paper contains simulation and measurement results for, output frequency, power consumption at different output load and circuit temperature.
