Abstract

A new look at the generalized structure of direct current differential amplifiers is described. The main analytical expressions for transfer function of the amplifier are presented. The particular cases of this structure are the classical schemes of both the voltage feedback op amp and current feedback one. As result of expression analysis the features of various particular cases are given. The discussed generalized circuit diagram and corresponding formulas for transfer function can be useful for the design of a whole range of amplifier units, built according to both a traditional and a non-traditional structures.
