Abstract

In this paper, a generalized admittance simulator is presented. The proposed circuit uses two operational transresistance amplifiers (OTRAs), one voltage buffer and three passive components. The proposed generalized admittance simulator can realize three simulators namely lossless grounded positive inductance simulator, frequency dependent negative resistance (FDNR) simulator and capacitance simulator/multiplier without any matching constraint. The non-ideality analysis of the circuit is also given. The workability of the proposed admittance simulator is shown through the implementation of second order band pass filter using inductance simulator, second order low pass filter using FDNR and variable capacitance low pass filter using capacitance multiplier. PSPICE simulation results are included to verify theory.
