Abstract
A low supply voltage logic circuit includes a first current source operable to generate a first current dependent on a first control signal and to generate a first leakage current. A second current source is operable to generate a second current dependent on a second control signal and to generate a second leakage current. A third current source has a third current path between the output terminal and the first supply voltage terminal and is operable to generate a third current through the third current path to compensate for the second leakage current. A fourth current source has a fourth current path between the output terminal and the second supply voltage terminal and is operable to generate a fourth current through the fourth current path to compensate for the first leakage current.
