CURRENT FEEDBACK AMPLIFIER BASED VOLTAGE MODE MULTI FUNCTION FILTER

Here we propose a new Voltage – mode biquadratic three input and Single output (TISO) multifunction filter based on two current feedback amplifiers (CFAs) four resistors and two capacitors. This second order filter circuit is capable of realizing various filter functions by choosing values of the three inputs variably. The natural frequency (ω0)can be tuned with passive components and the Q of the circuit is independent of (ω0) .The higher cascading capability of the circuit is ensured because of its low - output impedance. Further PSPICE-simulated results are in conformity with theoretical values.
