Level Restoration for Multi-valued Logic Circuits
نویسندگان
چکیده
Compared to binary logic, the multi-valued logic circuits provide very small chip size, higher speed, and small number of interconnections and simpler realization of logic functions. However, the main drawback of these circuits is the lower noise margin. The noise margin decreases as the radix of multi-valued system increases. Due to the low noise margins, it is necessary to restore or recover the nominal levels of the signal after a certain number of cascaded stages. In this paper a new current mode CMOS restoration circuit is presented and evaluated.

Introduction: The multi-valued logic (MVL) is an alternative to common binary logic. The arithmetic operations can be performed more efficiently, and faster, by increasing the radix of the system or the number of levels used, at the expense of reduced noise margin. Thus, it suffers from noise and parameter variations. Since the variations at each stage are added up, it is unavoidable to restore...

To further increase the speed of computation, this paper aims to design and implement digital circuits entirely within the domain of multi-valued logic. In a fourvalued logic circuit, each wire carries two bits at a time, each logic gate operates two bits at once, and each memory cell records two bits at one time. To make the multi-valued computation possible, this paper describes a simple four...
