Abstract :
The sensitivity of ring VCO designs based on the Maneatis delay cell to extrinsic noise is presented and comparisons are made. Perturbation projection vector and transient analyses are used to reveal the benefits and drawbacks of the designs using basic biasing, boosted biasing, and connected common-source methods.
