VDTA-Based Floating FDNR Simulator Topology

Abstract

An electronically tunable floating frequencydependent negative resistance (FDNR) simulator circuit is presented in this paper. The circuit is composed of only three voltage differencing transconductance amplifiers (VDTAs) and two grounded capacitors without any external resistors. The presented FDNR simulator can be tuned electronically by changing the transconductance value of the VDTA. As application examples, the fourthorder Butterworth bandpass and lowpass filters are simulated using the proposed tunable floating FDNR simulator. Finally, the simulation results using CMOS 0.35 μm TSMC process parameters are included to verify the theoretical analysis.
