The Effect of Device Parameter Variations on Programmable Majority Logic Arrays

Abstract

Molecular scale electronics has become an attractive alternative and even extension to existing microscale technologies as they migrate to the nanoscale. With recent research in the field of molecular and nano electronics, devices such as switches and resonant tunneling diodes (RTD) have been developed which exhibit properties such as rectification, hysteresis and negative differential resistance (NDR). These devices have been utilized to realize circuits that can implement both memory and logic structures. This work revolves around the robustness of these nanoscale devices when employed in nanoelectronic programmable majority logic arrays (PMLA), programmable logic circuits based on majority logic resulting from NDR. We also show the results of corner analysis of the circuit's performance under parameter variations, and describe the behavior requirements of the aforementioned molecular devices, especially those of molecular switches, for the system to function efficiently.
