Title: Digital leakage compensation circuit

Abstract: A digital leakage compensation circuit for compensating for leakage in a dynamic circuit includes a dummy precharge circuit, a dummy input circuit, a dummy evaluation circuit, a dummy latching circuit, a sense circuit and a storage circuit. The dummy circuitry matches the size and layout of corresponding precharge, input, evaluation and latching circuitry in the dynamic circuit so that the leakage can be accurately modeled. The sense circuit senses the leakage and generates a signal, stored in the storage circuit, which causes an adjustable latching circuit to provide additional leakage compensation in the dynamic circuit. Alternatively, the dynamic circuit may include a driving circuit with an adjustable trip point. The sense circuit provides the signal to the driving circuit to adjust the trip point to compensate for the leakage.
