Abstract

See full text

A feed-forward bias circuit biases body bias terminals of transistors of another circuit to compensate for PVT variations in the other circuit. In some aspects, the feed-forward bias circuit compensates for transistor process corners in a circuit by enabling the generation of different bias signals under different corner conditions. In some implementations, the feed-forward bias circuit is used to bias a delay circuit so that the delay circuit exhibits relatively constant delay characteristics over different PVT conditions.
