A device is disclosed for providing compensation current continuously to compensate for leakage current at the node of an electrical circuit, such as a chip. The device includes a dummy storage cell, a single staged current mirror circuit and a non reconfigurable keeper circuit. The keeper can be used to compensate for a wide range of leakage corners where the internal storage is located. The adaptive keeper circuit not only increases the robustness of the storage node against leakage caused by process variation but also improves the overall performance of the static storage device connected to the node.
