A novel active inverse memristor emulator with improved low frequency feature

Based on several active elements, a modified inverse memristor emulator is proposed, which presents better performance than the previous emulators. The published inverse memristor emulators with active blocks show that lobes’ size of pinched hysteresis loops (PHLs) shrinks early with decreasing the applied frequency, while the new one can show good cyclic hysteresis phenomenon when low frequency signal is applied. Obviously, the lobes’ area of the improved inverse memristor emulator widens faster than the existed active models with increasing frequency in the low frequency range. And the circuit model just only includes two second generation current conveyor (CCII), one analog voltage multiplier and six passive elements.The improved emulator is demonstrated by implementing LTspice simulations and verified by experiments. A comparison between the proposed model and the representative current-controlled one highlights the superiority of the former in the lower frequency range.
