ABSTRACT

A new biquadratic filter with three voltage-inputs and one voltageoutput and one current-output is presented. The filter employs two types of current conveyors, grounded resistors and grounded capacitors to realize the lowpass, highpass and bandpass responses by selecting different input signals. The proposed circuit has high input impedance, independent adjustments of angular frequency ω₀ and quality factor Q using capacitors and resistors, in addition to low active and passive sensitivities. Hspice simulation results are given to demonstrate the new proposed biquadratic filter.

Keywords: Current Conveyors, Biquadratic Filter, DDCC (Differential Difference Current Conveyor), CCII (Second-generation Current Conveyor).
