Abstract :
Compared to binary logic, the multi-valued logic circuits provide very small chip size, higher speed, and considerably 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.
