In this paper, two simple circuits are presented to emulate both memcapacitor and meminductor circuit elements. The emulation of these components has crucial importance since obtaining these high-order elements from markets is difficult when compared to resistor, capacitor and inductor. For this reason, we proposed Multi-Output Operational Transconductance Amplifier (MO-OTA)-based electronically controllable memcapacitor and meminductor circuits. To operate the MOS transistor as a capacitor, drain and source terminals are connected to each other. The memcapacitor behavior is obtained by driving the connected terminals with suitable voltage values. Only a few active and grounded passive components which are found in markets easily are used to emulate meminductive behavior. Furthermore, all passive elements in the circuit are grounded. All simulation results for memcapacitor and meminductor emulators are obtained successfully when compared to previous studies. For all analyses, MO-OTA is laid using the Cadence Spectre Analog Environment with TSMC 0.18 mu m process parameters and occupied a layout area of only 86.21 mu mx34.67 mu m.
