Memristor-based pulse width modulator circuit

This paper discusses the use of the memristor in one of the most important modulation techniques in communication field namely the pulse-width modulation. A fundamental two designs for memristor-based lead and trail PWM are discussed with mathematical analysis and PSPICE simulation results which show a great matching with the analytical formulation. Moreover, a third design which combine those two designs to generate a more accurate memristor-based center PWM is discussed with the appropriate analysis, numerical and PSPICE simulation results. The simulation results matches the theoretical analysis results and the proposed circuits enjoy simple design, small area and low power consumption. © 2016 IEEE.
