Single VDCC Based Memcapacitor Emulator Circuit without Using Passive Elements and Analog Multiplier

Abstract

In this work, a grounded charge-controlled memcapacitor emulator circuit based on a Voltage Difference Current Conveyor (VDCC) is presented. The proposed circuit is constructed with only one VDCC element and four MOSFETs. It has a transistor-based structure without the use of any passive components. The absence of any passive components makes the circuit eliminating the need for complicated analog components. The suggested circuit does away with the necessity for a mutator, which eliminates the need for an additional separate memristor emulator. The analog multiplier circuit is also not used. Additionally, the designed memcapacitor circuit allows for independent electronic control of both the fixed and variable components, adding to its flexibility and adaptability. To demonstrate the accuracy of the suggested circuit, a SPICE simulation was run using a VDCC constructed with 0.18 µm TSMC CMOS transistors.
