Abstract:
1. An integrated circuit configured for core circuit leakage control, the integrated circuit comprising: a core circuit configured to operate in a standby mode, the core circuit comprising a power terminal and a ground terminal; a first switch and a second switch, the first switch coupled between the power terminal and a power supply, the second switch coupled between the ground terminal and a ground supply, the first switch and the second switch configured to power ON and power OFF the core circuit to thereby control leakage associated with the core circuit; a first feedback circuit coupled with the first switch and the core circuit, configured to control an ON state and an OFF state of the first switch based on voltage at the power terminal during the standby mode to thereby maintain a logic state of the core circuit; and a second feedback circuit coupled with the second switch and the core circuit, configured to control an ON state and an OFF state of the second switch based on voltage at the ground terminal of the core circuit during the standby mode to thereby maintain the logic state of the core circuit; wherein the first feedback circuit comprises:
