Abstract
The paper proposes the topology and implementation of the shadow bandpass filter. The main advantage of this work is that the bandpass filter possesses the distinctively high-quality factor whereas the control of this quality factor is independent with the tunability of the characteristic frequency. The circuit configuration is realized and satisfactorily verified via PSpice simulation.
