摘要：

A new CMOS current starved voltage controlled ring oscillator (CSVCRO) topology is presented. The proposed voltage controlled oscillator was designed, analyzed and verified by simulating it in 0.35 mu m CMOS technology. The VCO architecture proposed in this work provides high linear relationship between oscillation frequency ranging from 0.71.75GHz over a control voltage ranging from 1.2--2V and results in a large tuning range of 75%. The phase noise achieved is -88dBc/Hz at an offset frequency of 1MHz. The linear frequency sweep is obtained without employing any additional compensation techniques resulting in less circuit complexity, die area and power consumption.
