Abstract
The leakage compensation circuit includes: a replica circuit of a circuit to be compensated, the replica circuit provides a replica leakage current equal to a leakage current of the circuit to be compensated; an amplifier having a first input coupled to the replica circuit and a second input coupled to a node to be compensated; a first resistance coupled between an output of the amplifier and the replica circuit; a second resistance coupled between the output of the amplifier and the node to be compensated; and wherein the replica leakage current is subtracted from the node to be compensated.
