Abstract
ABSTRACT A Differential Difference Current Conveyor Transconductance Amplifier (DDCCTA) based resistor tunable memristor emulator has been proposed in this work. The emulator can be used in both grounded and floating circumstances. The proposed design incorporates only one active block along with few passive components. Moreover, the circuit can operate in both incremental and decremental modes, by simply changing the input ports. The circuit demonstrates all the characteristics of an ideal memristor up to 6 MHz. The proposed model has been simulated using TSMC 0.18m process parameter and occupies an area of 51 × 42.5 m2 chip-area, excluding capacitor. The circuit’s reliability has been verified by studying non-ideal, non-volatile, Monte-Carlo, process corner variations analysis. The circuit applicability has been tested through series/parallel combinations. To validate the experimental demonstration, AD844AN and CA3080 have been used to make a prototype, which shows good agreement with theoretical and simulation results.
