ADAPTIVE THRESHOLD VOLTAGE CONTROL WITH POSITIVE BODY BIAS FOR N AND P-CHANNEL TRANSISTORS

摘要

A threshold control circuit for CMOS transistors wherein the voltage on the body of an n-channel reference transistor is controlled with a feedback circuit to produce a positive voltage on the body and decrease the threshold of the reference transistor to a desired value and the voltage on the body of a p-channel reference transistor is controlled with a feedback circuit to produce a negative voltage on the body and decrease the threshold of the reference transistor to a desired value.
