Transmission Delay Analysis Based on Memristor Gate Circuits

Memristors, as emerging nonlinear devices, exhibit great potential in implementing digital logic circuits. This paper is based on the Knowm memristor model, utilizing LTspice simulation software to simulate and verify basic logic gates. Physical memristor devices are used for testing, and the results of simulations and experiments are compared and analyzed. Frequency analysis is conducted on the propagation delay of logic gates. The study compares and analyzes differences and their causes through multi-dimensional and multi-faceted approaches. It theoretically elaborates on the frequency characteristics and physical mechanisms of the propagation delay in memristor logic gates, aiding in better utilization of the frequency characteristics of memristors and providing a reference for the design of memristor logic gates in the future.
