Abstract :
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 of active elements and grounded passive components, permitting orthogonal adjustment of quality factor Q and ωp where no element matching conditions are imposed. The passive sensitivities are shown to be low
