ABSTRACT:
An integrated circuit, that includes: (i) a power gating switch, the power gating switch includes (a) an input port for receiving an input supply voltage; (b) an output port for outputting an output supply voltage; and (c) a control port for receiving a control signal that determines a difference between a value of the input supply voltage and a value of the output supply voltage; (ii) a power gated circuit, coupled to the output port of the switch, for receiving the output supply voltage; (iii) a mode indicator generator for generating a mode indicator that indicates of a desired mode of the power gated circuit; (iv) a leakage indicator generator for generating a leakage indicator that indicates of a leakage level of the power gated circuit; and (iv) a control circuit, for receiving the mode indicator and the leakage indicator, and for selecting the value of the control signal based on the mode indicator and on the leakage indicator.
