Leakage calibration

摘要

An integrated circuit and a method for efficiently operating integrated circuit devices. The integrated circuit includes an input that is configured to receive a first current which is representative of a leakage current drawn by leakage in a portion of the integrated circuit. The integrated circuit includes a leakage calibrator that is configured to compare the first current to a current required to perform a switching operation and output a value indicative of the leakage.

1. An integrated circuit, comprising:
an input configured to receive a first current from a first functional circuitry block of the integrated circuit which is representative of a leakage current drawn by leakage in the first functional circuitry block; and a leakage calibrator configured to compare the first current to a second current required to perform a switching operation that halts power to the first functional circuitry block by generating a first signal based on the first current and a second signal based on the second current and performing a comparison of the first signal and the second signal to generate an output signal.
