Abstract
This paper presents a new versatile active circuit for the realization of impedance converter, ideal grounded inductance, FDNR, and R/C multipliers through appropriate selection of passive elements. The proposed circuit is realized using low voltage CMOS Operational Floating Conveyors (OFC) and grounded passive components, without using any matching constraints. This makes it attractive for IC implementation. As an application the proposed grounded inductance simulator is used to realize a multifunctional filter, which provides low pass (LP), band pass (BP) and high pass (HP) responses. The circuit also enjoys attractive features, such as, low supply voltage, low component count, low sensitivities, high Q and independent Q-tuning without affecting its pole frequency. Simulation results show excellent performance with low voltage of ± 0.75 volts.
