Abstract

A circuit and method for reducing the leakage current drawn by a transistor when it is inactive. In a first implementation, a circuit selectively drives the gate of a transistor to a voltage level above a source voltage. As a result, the gate-source voltage is reversed and the leakage current flowing through the transistor is substantially reduced. In a second implementation, a circuit selectively biases the well of a transistor to a voltage level above a normal bias voltage. As a result, the voltage-current characteristics of the transistor are modified so that the leakage current is substantially eliminated.
