SYSTEM AND METHOD FOR DESIGNING A LOW LEAKAGE MONOTONIC CMOS LOGIC CIRCUIT

摘要

A computer system for designing a low leakage monotonic CMOS logic circuit. The system performing the computer implements steps of: (a) specifying a reference PFET having its threshold voltage and its gate dielectric thickness and a reference NFET having its threshold voltage and its gate dielectric thickness; (b) synthesizing a schematic circuit design with standard design elements, the standard design elements including one or more reference PFETS and one or more reference NFETs; (c) analyzing one or more circuits for logic stages having predominantly high input logic states or predominantly low input logic states; (d) selecting one or more logic stages determined to have predominantly high input logic states or predominantly low input logic states; and (e) replacing the standard design elements of the selected logic stages with reduced current leakage elements.
