Design Consideration for Active–Only Memcapacitor Emulator Circuits

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.
