A novel noninteracting Electronically Tunable Universal Filter

A noninteracting electronically tunable universal filter is proposed in this paper. The proposed circuit can simultaneously realize highpass, lowpass and bandpass transfer functions without changing the circuit topology. Also, the circuit is implemented by using four CCCIIs with controlled current gain and two grounded capacitors which is suitable for IC implementation. Moreover, the proposed circuit can be simply modified to achieve bandstop and all pass responses. The parameters omega, Q and H₀ of the filter are independently tunable. The PSPICE simulation results show that the proposed filter performs its function property
