Abstract:
A circuit comprising:a first leakage control transistor coupled to receive a first supply voltage and to be coupled in series with an internal circuit block that performs a particular function, the internal circuit block being coupled to receive a high supply voltage and a low supply voltage, the first supply voltage being one of the high or low supply voltages; anda gate drive circuit to apply a boosted gate drive voltage to a gate of the leakage control transistor during an active mode of the internal circuit block and to apply a standby gate voltage to the gate during a standby mode of the internal circuit block, the boosted gate drive voltage being higher than the high supply voltage if the first leakage control transistor is an n-type transistor, the boosted gate drive voltage being lower than the low supply voltage if the first leakage control transistor is a p-type transistor.
