Abstract
Circuits, methods, and systems are presented for managing current leakage in an electronic circuit. One circuit includes a keeper circuit, and a controller. The keeper circuit supplies current to a leaker circuit, which is experiencing current leakage, to compensate for the current leakage. Further, the controller provides to the keeper circuit a control signal that is based on the current leakage. The control signal has a cycle equal to the cycle of a clock signal, and the control signal is a pulse having a first value during a first period, and a second value during a second period of the pulse. The keeper circuit provides a current to the leaker circuit during the first period and the keeper circuit withholds the current to the leaker circuit during the second period, where the durations of the first period and the second period are based on the current leakage.
