In this contribution, nine new Grounded Inductance Simulators (GISs) using a single Multiple-Output Current Controlled Current Conveyor Transconductance Amplifier (MO-CCCCTA) and one grounded capacitor are proposed. Among them, two are lossless types and seven are lossy types. The use of a single grounded capacitor makes the circuits suitable for fabrication. All the proposed circuits are electronically tunable through the bias currents of MO-CCCCTA. Furthermore, no component matching conditions are needed for realizing them. The designed circuits are verified through PSPICE simulator with ± 0.9 V power supply. The simulation results show that for all the proposed circuits: maximum operating frequencies are about 12 MHz, power dissipation is less than 0.784 mW, Total Harmonic Distortions (THDs) are under 8.09%, and maximum output voltage noise at 1 MHz frequency is 14.094 nV/√Hz. To exhibit the workability of the proposed circuits, they are used to design band-pass, low-pass filter, parallel RLC resonator, and parasitic inductance cancelator.
