Abstract

A simple and elegant method to realize a Frequency-Dependent Negative Resistance (FDNR) with only one operational amplifier is presented. The input arid output admittances of the proposed amplifier configuration realize either a frequency-dependent negatives resistance or a combination of frequency-dependent negative resistance with series-parallel EC configuration. Infinite input impedance is realized by invoking certain constraints on the elements of the network. Input and output admittance/impedance sensitivity analysis is also presented.
