Fractional Order Mem-Inductor and Mem-Capacitor Mutator using Single DXCCTA

Abstract

The paper introduces new designs for fractional-order mem-element mutators utilizing an active component known as the dual-X current convey or transconductance amplifier (DXCCTA). These mutators serve as both meminductor and memcapacitor emulators. The proposed designs incorporate just one DXCCTA, one memristor and one fractional-order capacitor which is implemented using a constant phase element. The mem-element mutators can operate in both floating and grounded modes. An extensive analysis of the circuits is presented, addressing ideal, and non-ideal analysis. The theoretical performance of the designed mem-element mutator circuits is validated through SPICE simulations using 0.18 µm technology. The proposed mutator designs demonstrate a high operating frequency (up to 800 kHz), low power consumption (2.5 mW), low operating supply voltages (±1.25 V) and robust performance across variations in process, voltage, and temperature. The non-volatility of the proposed emulators is also tested.
