Abstract
A differential amplifying circuit includes a pair of main amplifying circuits (5a, 5b) each having at least three input terminals and at least one output terminal, and a pair of auxiliary amplifying circuits (6a, 6b) each having at least one input terminal. Complimentary inputs (D1, D1) are connected to the input terminals of said pair of auxiliary amplifying circuits (6a, 6b), the outputs (D2, D2) of the main amplifying circuits (5a, 5b) are connected as crossing feedback inputs to at least a pair of input terminals of said pair of main amplifying circuits (5a, 5b), the complimentary inputs (D2, D2) are also connected to the other at least one pair of input terminals, and the outputs of said auxiliary amplifying circuits (6a, 6b) are further connected to the further at least pair of input terminals.
