Abstract
A bandpass filter is presented which allows variation of bandwidth while passband gain remains constant. The presented bandpass filter relies on feedforward (as opposed to feedback) to compensate for losses within the bandpass filter. Two feedforward circuits are shown, one a current source and the other a voltage source in series with a resistance.
