Abstract
This document discusses methods and apparatus for preventing or reducing sub-threshold pass gate leakage. In an example, an apparatus can include a pass gate configured to electrically couple a first node with a second node in a first state and to electrically isolate the first node from the second node in a second state, control logic configured to control the pass gate, wherein the control logic includes a supply rail, and an over-voltage circuit configured to compare voltages received at a plurality of input nodes and to couple an output to an input node a highest voltage. In an example, the output of over-voltage circuit can be selectively coupled to the supply rail.
