Memristor-based emulator for use in digital modulation

摘要

A memristor-based emulator including a memristor circuit for use in digital modulation that includes a first current feedback operational amplifier (CFOA) having multiple terminals in communication with a capacitor C_d and in further communication with a resistor R_i. A second CFOA having multiple terminals is in communication with the first CFOA and is adapted to be in further communication with a voltage v_M to provide an input current i_M for integration by a capacitor C_i. A nonlinear resistor is in communication with the second CFOA. A third CFOA having multiple terminals is in communication with the nonlinear resistor and is in further communication with the first CFOA and a resistor R_d. The third CFOA and the resistor R_d act as an inverting amplifier associated with the nonlinear resistor to increase a current gain to increase a difference between ON and OFF values of a resistance of a realized memristor.
