Abstract

The impact of gate fan-in and fan-out limits on digital circuit delay is discussed with a set of benchmark circuits. This research presents the advantages of exploiting the ability of optoelectronic gates to perform both logic operations and optical interconnections with systematic optimization. It is possible for gate-level optical interconnected optoelectronic circuits to compete with their pure silicon counterparts in terms of the combinational circuit delay and system clock rate.
