Abstract

A quasi-equal inductor filter and its corresponding multilayer realization are proposed in this paper. The circuit transformation is performed using the Norton transformation. In the proposed filter, ratio between the largest and smallest component values is reduced, which makes the design of components much easier. Meanwhile, by carefully selecting the transformation ratio, all grounding inductors are equal in value. As a result, the multilayer filter design is simplified because only one instance of grounding inductors needs to be designed instead of three. An experimental prototype is fabricated and measured. The measurement result agrees well with the desired one, which shows the effectiveness of proposed filter.
