Abstract
An electronic circuit includes a switchable circuit domain that operates in a RUN mode and a STANDBY mode and receives a supply current from a core power supply. A power regulator is connected between the core power supply and the switchable circuit domain to regulate the supply current provided to the switchable circuit domain when the electronic circuit is in the RUN mode. A capacitor is connected between the power regulator and ground and is charged by a refresh circuit when the electronic circuit is in the STANDBY mode. The refresh circuit maintains a voltage across the capacitor when the electronic circuit is in the standby mode, which reduces the time for the electronic circuit to transition from the STANDBY mode to the RUN mode.
