New Current-mode Three-Inputs One-output Multifunction Filter with Independent Tune

In this study, a three-inputs single-output current-mode analog biquadratic filter, based on second generation current controlled current conveyor (CCCII) is presented. The proposed filter uses four CCCIIs and two grounded capacitors without any external resistors, which is well suited for integrated circuit implementation. The circuit gives five standard transfer functions, namely, lowpass, highpass, bandpass, notch and allpass filters with independent control of quality factor and pole frequency by electronic method. Each function response can be selected by suitably selecting input signals with digital method. The filter does not require double input current signal. Moreover, the circuit possess high output impedance which would be an ideal choice for current-mode cascading. The PSPICE simulation results, using CMOS CCCII in 0.25μm TSMC CMOS technology, are included to verify the workability of the proposed filter. The given results agree well with the theoretical anticipation. Streszczenie.
