Wide band feedback amplifiers

Summary form only given. An approach to the problem of the design of transistor wide-band feedback amplifiers is given. Choice of feedback circuit configurations for the stabilization of amplifier circuit transconductance, transresistance, and current gain are discussed in terms of an idealized phase-reversing amplifier. A composite stage including two transistors which may be made to approach this idealized amplifier is described, including considerations of biasing, asymp totic high frequency cutoff characteristic, and composite hybrid parameters.
