Insensitive current-mode universal filter using dual output current conveyors

A new current-mode universal tilter with single input and three outputs emp loying only three dual output current conveyors and five grounded passive e lements is presented. The proposed filter realizes three filter functions s imultaneously, all at high impedance outputs. No component matching is requ ired and all the passive and active sensitivities are low. Furthermore, the filter can also realize the notch and all-pass responses. Orthogonal contr ol of the natural angular frequency and the quality factor is achieved.
