Abstract
Increased gain stability and gain-bandwidth product result from the use of inverse feedback in an intermediate-frequency amplifier. Improvement in gain stability is related to the number of cascaded stages, the stage gain, and the magnitude of the feedback. A circuit is described which uses feedback over a pair of cascaded stages. Generalized selectivity curves for this feedback couple axe shown, and the design procedure is outlined. A description of an experimental amplifier concludes the paper.
