A new generalized structure of direct current differential amplifier is described. The main analytical expressions for transfer function of the amplifier are presented. The particular cases of this structure are classical schemes of both the voltage feedback op amp and current feedback ones. As a result of expression analysis the features of various particular cases are given.
