US 2002/0162078 A1 · Digital logic circuits used to design integrated circuits

Abstract

A method and system for constructing, designing, and using a family of logic circuits based on methods of interconnecting transistors (or more generally, switches). The method includes the selective use of functionally redundant transistors to achieve target objectives, such as speed of operation, power dissipation, control over switching capacitances, noise characteristics, signal integrity etc. In accordance with the present invention, multiple topologies may be incorporated into the implementation of a single dynamic transistor topology. The logic circuit family provides flexibility by implementing different topologies for the various functionally redundant sub-networks of transistors. The method is applicable to any network of transistors whose characteristics depend, at least in part, on its implementation topology.
