ABSTRACT:
An apparatus for reducing current leakage between an input locus and at least one power rail for a system includes, for each respective power rail: (a) A first diode unit coupled between the input locus and a coupling locus. The first diode unit is configured to effect substantially zero potential drop during normal operation of the apparatus. (b) A second diode unit coupled between the coupling locus and the respective power rail. The second diode unit is configured to present no forward bias during normal operation of the apparatus. The first and second diode units cooperate to effect current flow between the input locus and the respective power rail during a predetermined operational condition of the apparatus.
