Switching network logic approach to sequential MOS circuit design

摘要

A novel, systematic approach to sequential MOS circuit design is described. The approach aims at minimizing the number of transistors needed to implement a given switching function. The techniques used are based on the switching network logic (SNL) approach, which was previously introduced as a systematic method of designing MOS combinational logic circuits. The authors extend the approach to sequential MOS circuit design. Examples are given to show that the proposed method reduces the number of MOSFETs as compared to existing design methods. A CAD (computer-aided design) program based on the SNL approach is presented as a finite state machine generator.
