This paper reports five new single-input multiple-output current-mode multifunction filter circuits which can simultaneously realise three basic filter functions all at high impedance outputs. The circuits employ only the same type of active elements, grounded passive components, and no element matching conditions are imposed. The filters permit orthogonal adjustment of the quality factor Q and angular resonant frequency omega(0). The active/passive sensitivities are shown to be low.
