A new high output impedance current-mode universal filter with single input and three outputs using dual output CCIIs

This paper presents a new current-mode universal filter using dual output current conveyors. The proposed filter can simultaneously realize three basic filter functions all at high impedance outputs. The circuit employs only the same type active elements and grounded passive components. The resonant angular frequency and the quality factor can be orthogonally controllable. The passive sensitivities are shown to be low. PSPICE simulation results are also included.
