On the realization of the FDNR simulators using only a single current feedback operational amplifier

In this paper, two new circuits for realization frequency dependent negative resistance (FDNR) depending on the passive component selection are proposed. Also, two FDNRs using a canonical number of elements, a CFOA, two resistors and maximum two capacitor, are developed. The proposed FDNR circuits do not need critical component matching constraints. Also, simulation results using SPICE program are given for the first introduced FDNR simulator to verify the theory and to exhibit the performance of the circuit.
