Circuits, and methods for reducing standby leakage power in Integrated Circuit (ICs) are disclosed. In an embodiment, an IC includes a core circuit, a first switch and a second switch, where the first switch is coupled between a power terminal of the core circuit and a power supply and the second switch is coupled between a ground terminal of the core circuit and a ground supply. The first switch and the second switch are configured to power ON and OFF the core circuit. The IC includes a first feedback circuit configured to control ON and OFF states of the first switch based on voltage at the power terminal, and a second feedback circuit configured to control ON and OFF states of the second switch based on voltage at the ground terminal of the core circuit during the standby mode for maintaining the logic state of the core circuit.
