Abstract
A reverse biasing logic circuit is disclosed for limiting standby leakage electric current losses during circuit operation. The circuit includes a logic function circuit having one or more logic transistors that receive an input and perform a logic function operation to generate an output. A power source transistor connects to the logic function circuit and receives a control signal that changes node voltages of the one or more logic transistors between an active mode and a standby mode. During the standby mode, the power source transistor causes reverse biasing of at least one of the one or more logic transistors which prevents a leakage electric current flow between the power source transistor and the one or more logic transistors.
