In this study, a new current-mode current-controlled universal filter with
single input and three outputs is presented. The proposed circuit uses sing
le-output current controlled conveyors (CCCIIs) and can simultaneously real
ize lowpass, bandpass and highpass filter functions all at high impedance o
utputs. Realization of notch and allpass responses does not require additio
nal active elements. The circuit enjoys independent current-control of the
parameters w(0) and w(0)/Q without disturbing the gains of the lowpass, ban
dpass and highpass filters. Both its active and passive sensitivities are l
ow.
