面向多值逻辑计算的基于CNFET的三元逻辑单元库设计
Design of CNFET-based ternary cell library for multi-valued-logic computing
摘要
Abstract
Compared to binary logic,ternary logic offers more logic states,endowing ternary logic-based circuits with advantages including smaller area,higher utilization,improved transmission efficien-cy,and enhanced security.This paper implements fundamental ternary logic gates using commonly avail-able carbon nanotube field-effect transistors(CNFETs),establishes a functionally complete ternary logic library,and proposes a method to reduce switching delay by minimizing the CNFET's physical channel lengthand and source/drain length.Based on the developed ternary logic library,a 1-bit multiplier circuit was designed and implemented.HSPICE simulations verified both the circuit performance and the effec-tiveness of the proposed delay reduction method,demonstrating an average 47 ps reduction in switching delay compared to prior ternary 1-bit multipliers.In the actual circuit application,this paper builds the ternary logic cell library that can be used for higher order circuit synthesis and physical design of the cir-cuit.The method to lower the ternary circuit switching delay time for the future,represented by high-performance chip microprocessor and artificial intelligence to lay a good foundation for very large-scale integration.关键词
