Analog and Digital Applications of 4-T Based Memristor Emulator

Abstract

Since the postulation of memristor, numerous memristor emulator networks have been proposed using linear/non-linear elements with active and passive devices to emulate the behavior of memristors for practical applications. Some unique characteristics of memristors are—pinched hysteresis I-V curve, non-volatility, frequency dependent, and dependent on the direction of current flow. Moreover, its ability to overcome the size limitations set by Moore’s law makes it an exciting component with many desirable characteristics. In this paper, analog and digital applications of memristor are proposed using a memristive emulator circuit that satisfactorily emulates the behavior of a memristor without employing any complex circuit elements. The emulator circuit referenced is 4-T-based circuit that is used as a fundamental block in the proposed designs. Logic gates, half adder, and full adder are realized in digital applications and Relaxation Oscillator in analog application, respectively. The power dissipation of the circuits are also analyzed. All the proposed digital circuits are simulated in Cadence Virtuoso ADE using gpdk 45 nm technology and analog application using gpdk 180 nm technology.
