| Abstract: | A three- input and one output voltage-mode (VM) universal biquadratic filter using a single current-feedback amplifier (CFA), a single operational transconductance amplifier (OTA), a single resistor and two capacitors is presented. The circuit without requiring component matching is capable of realizing from the same configuration all the standard filtering responses viz. lowpass (LP), highpass (HP), bandpass (BP), notch (BR), and allpass (AP). The cut off frequency ωo and bandwidth ωo/Q are independently tuneable. The low sensitivity figures is the additional advantage of the circuit. The circuit has been simulated using personal computer-simulation program with integrated circuit emphasis (PSPICE) and results are found to be in close conformity with theoretical analysis. |
