Abstract
A low-leakage circuit including a switch having an input node, gate, bulk region, and pin node, a comparison circuit configured to determine and output a greater of two voltages of the switch, a latching circuit connected to the comparison circuit and configured to bias the gate and the bulk region of the switch using the greater of the two voltages, and a shorting circuit configured to control a voltage at the bulk region to ensure that no leakage current flows from the pin node.
