Abstract

A voltage differencing buffered amplifier (VDBA) and a current differencing buffered amplifier (CDBA) are used in the proposed compact meminductor emulator design. The proposed emulator reduces the passive components number by utilizing parasitic components of CDBA to obtain a compact layout. This feature also aids in the realized circuit’s ability to operate at a high frequency. The element in the suggested design has memory of its previous state, since the effective meminductance is dependent on the total charge stored on the capacitors. By altering the capacitance values, pinched hysteresis loops between magnetic flux (Φ) and current (i) are shown throughout a broad frequency range (1 kHz to 3 MHz). Both incremental and decremental hysteresis assessments, non-volatility measures, and transient response tests verify that the suggested emulator is operating correctly. The theoretical predictions are closely matched with LTspice simulations utilizing 0.18 µm process characteristics. The non-ideal analysis of the suggested configuration verifies the accuracy of the derived expressions and simulation results. Lastly, the meminductor practical application in actual circuits is confirmed by incorporating it into a chaotic oscillator.
