An active inductor employing a new four terminal floating nullor transconductance amplifier (FTFNTA)

Abstract In this manuscript, two different topologies are presented for the realization of a conventional filter/inverse filter using the Four Terminal Floating Nullor Transconductance Amplifier (FTFNTA). The first topology can synthesize the inverse low-pass (ILP), inverse high-pass (IHP), and inverse band-pass (IBP) filter with applicable impedance choices. Subsequently, another topology that can synthesize conventional low-pass (LP), and band-pass (BP) active filter, as well as inverse high-pass (IHP), and inverse band-pass (IBP) filter from the same circuit topology with a viable solution of impedances as resistor/capacitor. To verify the workability of both topologies, SPICE simulation is performed using 180nm CMOS TSMC technology.

<p>In this paper we propose a synthesis of microwave active filters having Butterworth and Chebyshev responses in the frequency range 1GHz-2GHz. The filter fundamental block, used to build an active inductor, consists of CMOS-based Operational Transconductance Amplifier (OTA) circuits. These amplifiers are made out of simple current mirror using MOS transistors. The simulation procedure has been carried out through PSPICE software showing good performances regarding scattering parameters in terms insertion losses, of out-of-band rejection and phase.</p>
