Design considerations of bandpass LC filters for RF applications

This paper presents different design considerations of active Q-enhanced LC bandpass filters. An architecture for implementing high order filters is proposed. It uses electric coupling to emulate the effect of the transformer, thus providing bandwidth tuning with small passband ripple.
