Demonstration of a NEMS Comb Drive for the Use of High Speed, High Efficiency Analog Multiplications

This document proposes a novel application of nanoelectromechanical system (NEMS) comb drives in the use of analog computations, specifically multiplication. Through the use of simulations, we demonstrate the feasibility of performing simple, scalar multiplications of analog values using a single NEMS comb drive. Using state-of-the-art NEMS technology, we find that a single NEMS comb drive can reach a theoretical computational efficiency of over 4,000 TOPS/W, with a throughput of over 600,000 multiplications per second. This is ten times higher than the previous maximum efficiency demonstrated by analog or analog-digital hybrid multipliers in the literature.
