Claim:
1. An apparatus comprising: a first node to provide an un-gated power supply; a second node to provide a threshold dependent supply having a value directly determined by a diode threshold; an inverter with an input and an output, the inverter coupled to the first and second nodes, the inverter to receive the un-gated power supply at its power supply node, and to receive the threshold dependent supply for supplying a reference supply at its reference node; and a transistor with its gate terminal coupled to the output of the inverter, the transistor to provide gated power supply to one or more logic units; a keeper transistor comprising a first source/drain node coupled to the output of the inverter and a second source/drain node coupled to one of the first node and a ground node.
