Electronically tunable floating resistor

Abstract

A new design for an electronically tunable floating resistor is proposed The proposed circuit can be realized a positive or negative resistor without changing the circuit topology. Also, the resistance values of the circuit can be tuned electronically. The proposed circuit is based on only one second-generation current controlled conveyor, which is easy to be fabricated in IC technology. Simulation results are obtained to show adequate agreement with theory. © 2004IEEE.
