A New Electronically Tunable Current Differencing Transconductance Amplifier Based Meminductor Emulator and its Application

Abstract

In this paper, a simple electronically tunable meminductor emulator based on current differencing transconductance amplifiers (CDTAs) and passive components has been suggested. The proposed CDTA-based emulator is unique as it is memristor-less, uses only a single type of active building block, has simpler circuitry, is electronically tunable, and uses only grounded capacitors. The proposed emulator shows acceptable performance over a broad frequency range. Using the LTSpice tool and 0.18μm CMOS technology, simulations were conducted to test the performance of this emulator. The proposed meminductor emulator's functionality has been examined for the chaotic oscillator and adaptive learning circuit. The satisfactory performance of these circuits confirms the use of the proposed emulator in a practical environment.
