Abstract

A low leakage logic circuit. The low leakage logic circuit includes a control circuit for logic circuit. The control circuit has a first transistor, a second transistor, a third transistor, a first diode, a first resistor and a second resistor. When the control circuit is ON, a first circuit path in the logic circuit is supplied with a first voltage from the source terminal of the third transistor. This voltage acts as a logic output and has the ability to source current at output terminal of the logic circuit. When the control circuit is OFF, a second circuit path in the logic circuit is supplied with a second voltage from the control circuit which is lower than the turn-on voltage of the second circuit path. This voltage is insufficient to turn ON the logic circuit, hence no current flows into the logic circuit.
