This paper presents a new single-input multi-output type current-mode multifunction filter. 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 permitting orthogonal adjustment of quality factor Q and omega (p) where no element matching conditions are imposed. The passive sensitivities are shown to be low.
