VOLTAGE MODE UNIVERSAL BIQUADRATIC FILTER USING FTFN AND OTA

A single input and five outputs voltage mode universal biquadratic filter using two four terminal floatingnullor (FTFNs), two operational transconductance amplifiers (OTAs), four resistors and two groundedcapacitors is presented. The circuit is capable of realizing the entire standard filters viz-low pass, highpass, band pass notch and all pass simultaneously. The circuit offers the advantageous feature of havinghigh input impedance and the use of grounded capacitors makes the circuit suitable for cascading of higherorder filter. The filter performance parameter resonance frequency ω0 and quality factor Q can be controlorthogonally.
