ABSTRACT:
In one embodiment, an apparatus for reducing leakage in an electronic circuit (e.g., a CMOS circuit) includes a power switch transistor configured to selectively couple or decouple a voltage to a logic portion of the electronic circuit. The power switch transistor receives a first voltage during an active mode of the electronic circuit and receives a second voltage during a sleep mode of the electronic circuit. The power switch transistor has a bulk region that is biased using the first voltage during sleep mode. The power switch transistor has a gate region that is biased using the first voltage during sleep mode.
