169-174A current-mode and transimpedance-mode universal biquadratic
filter with single input and multi-outputs using three multiple outputs
second-generation current conveyors (MOCCIIs), five resistors and two grounded
capacitors is presented. The proposed circuit can realize current-mode notch, bandpass
and lowpass responses, simultaneously. The current-mode highpass and allpass
responses can be obtained by interconnection of relevant output currents. Moreover,
the transimpedance-mode highpass, bandpass, lowpass, notch and allpass filters
can also be obtained, simultaneously, from the proposed circuit
