A multiple-valued algebra for modeling MOS VLSI circuits at switch-level is proposed in this paper.Its structure and properties are studied.This algebra can be used to transform a MOS digital circuit toa switch-level algebraic expression so as to generate the truth table for the circuit and to derive aBoolean expression for it.In the paper,methods to construct a switch-level algebraic expression for acircuit and methods to simplify expressions are given.This algebra provides a new tool for MOS VLSIcircuit design and analysis.
