Abstract :
A new three-input single-output voltage-mode universal biquadratic filter with high-input impedance using only three plus-type second-generation current conveyors (CCIIs) is presented. The proposed configuration uses only two capacitors and two resistors and can realize all the standard filter functions, that is, high-pass, bandpass, low-pass, notch, and allpass filters without changing the passive elements. The proposed circuit has no requirements for component matching conditions. The use of only plus-type CCIIs simplifies the configuration
