A New Multiplier-less Memristor Emulator for Analog and Digital Applications

Abstract

A charge controlled memristor circuit using the most adaptable analogue block called Current Backward Transconductance Amplifier (CBTA) and Operational Transconductance Amplifier (OTA) along with few passive elements is introduced. It uses only one CBTA, one OTA, three resistors and one capacitor for emulating grounded memristor. The proposed memristor emulator is simulated in Cadence Virtuoso tool using standard CMOS  technology including post-layout simulation of CBTA and OTA silicon components. All the CMOS transistors operating with the ±1.2 V DC supply voltage. Moreover, this paper demonstrates the proposed memristor use in the analog and digital domains. Furthermore, off-the-shelf components (IC AD844AN and CA3080EZ) and passive components are used in an experimental setup to verify the proposed circuit.
