PRACTICAL LOW-COST CMOS REALIZATION OF COMPLEX LOGIC FUNCTIONS

This paper explores the use of threshold gates for the design of complex logic functions. The usefulness of the approximation is determined by the efficient CMOS realization proposed for the threshold gates. New implementations are presented for two different circuits, the Muller C-element and the Losq’s voter for self-purging redundancy, which illustrate the feasibility and versatility of the proposed technique and its potential as a low-cost design technique for CMOS technologies. Experimental and simulation results confirm our expectations and prove the suitability of the proposed circuits under low-voltage power supply conditions.
