“…The mutation of memristive systems into universal memcapacitive and meminductive emulators have also been considered by some authors, as the case of Taşkiran et al [60]. In this work, the authors proposed a simple current backward transconductance amplifier (CBTA) to implement a universal mutator based on the scheme exhibited in Figure 17a, whose equivalent input impedance in the Laplace domain can be expressed as:…”

“…As in the case of the circuit proposed by in Ref. [60], this mutator can be used to achieve a straightforward transformation between a memristor and either a memcapacitor or a meminductor by just modifying the combination of its different impedances. In both cases, either the memcapacitor (Figure 18b) or the meminductor (Figure 18c), the constitutive equation of the emulated device can be derived from the relation between the current and the voltage in Z 1 .…”

Memcapacitor and Meminductor Circuit Emulators: A Review

et al. 2021

In 1971, Prof. L. Chua theoretically introduced a new circuit element, which exhibited a different behavior from that displayed by any of the three known passive elements: the resistor, the capacitor or the inductor. This element was called memristor, since its behavior corresponded to a resistor with memory. Four decades later, the concept of mem-elements was extended to the other two circuit elements by the definition of the constitutive equations of both memcapacitors and meminductors. Since then, the non-linear and non-volatile properties of these devices have attracted the interest of many researches trying to develop a wide range of applications. However, the lack of solid-state implementations of memcapacitors and meminductors make it necessary to rely on circuit emulators for the use and investigation of these elements in practical implementations. On this basis, this review gathers the current main alternatives presented in the literature for the emulation of both memcapacitors and meminductors. Different circuit emulators have been thoroughly analyzed and compared in detail, providing a wide range of approaches that could be considered for the implementation of these devices in future designs.

“…A comparative study of the proposed mem-element emulator with an existing mem-element emulator has been undertaken in Table I. From the table, it can be observed that,  Unlike circuits proposed in [15], [17] and [19] whose memcapacitor properties depend upon the memristor, the proposed grounded and the floating circuit is designed without using a memristor.  Memristor, Memcapacitor, and Meminductor proposed in [20] was independent.…”

“…However, this model cannot be used for practical circuits. Mutators were developed for transforming memristor to memcapacitor or meminductor in [15][16][17][18][19][20]. However, the properties of these memcapacitor depend upon the used memristor which uses excessive components.…”

This paper proposes a charged controlled emulator model for memristor and memcapacitor using second-generation Current Conveyor (CCIIs) and Analog Multiplier (AM). The grounded and floating memelement circuits have been designed using two CCIIs and one multiplier in addition to some passive components. The grounded type of design requires three resistors and three capacitors while floating design necessitates only two resistors and two capacitors. With the help of a switch, the proposed design can be easily switched into a memristor or memcapacitor. The proposed emulator model has been theoretically analyzed and simulated in PSpice to substantiate the effectiveness and accuracy. The practicability of the circuit has been established using commercially available ICs AD844AN and AD633JN. Non-linear characteristics of the proposed memristor emulator have been used to design a chaotic system.

“…As the memristive elements are characterized by the wellknown pinched, or zero-crossing hysteresis twist in currentvoltage space, the fingerprint of the memcapacitor is the pinched loop in the voltage-charge space [11]. In some implementation, memcapacitor behavior can be obtained using mutator which converts memristor behavior to memcapacitor [12][13]. These circuits employ perfect memristor to implement the memcapacitor, which may be problematic in case the limitations of the involved memristor are not well understood or its optimized design is not available.…”

In this paper, a simple memcapacitor emulator circuit using only active elements is presented. Instead of using any bulky passive components, the proposed circuit makes use of the intrinsic capacitors of MOSFETs. As a result, the circuit took up significantly less area on the IC environment. In addition, a modification technique is proposed to extend the operating frequency range of the emulator, which might broaden the circuit's application possibilities. Considering the basic non-idealities of the circuit, a more realistic formulation of the memcapacitance value is derived. Detailed simulations utilizing the 0.18 µm CMOS Cadence design tool are used to validate all theoretical aspects as well as the circuit's appropriate functionality.
