Resistorless realization of tunable floating lossy inductors using single MO-CCCCTA

In this study, a series RL type and a parallel RL type floating inductance simulators (FISs) are proposed. Only one multiple-output current controlled current conveyor transconductance amplifier (MO-CCCCTA) and one grounded capacitor are sufficient to realize these simulators. Nevertheless, both the recommended FISs have a floating capacitor fit to be very effective in today’s integrated circuit fabrication. The proposed inductance simulator circuits are resistorless and their parameters can be tuned electronically. Furthermore, the proposed simulators require no matching conditions. Non-ideal as well as parasitic analysis of the proposed circuits has been carried out to strengthen the design idea. The workability of the circuits is tested through the construction of a second order low pass filter using a series RL inductance simulator and a parallel resonant circuit using parallel RL inductance simulator. PSPICE simulations with 0.18 µm TSMC CMOS technology have also been included to confirm the performance of the proposed simulators.
