Abstract

PURPOSE:To secure a stable output bias level for both output parts to which an equal input is applied, by setting the reference to decide the two output bias levels to the positive and negative poles of a power source and at the same time applying a DC negative feedback to the input part from either one output. CONSTITUTION:A differential amplifying circuit consists of transistors(TR) 1 and 2 plus the current souce 5, and the collectors of TRs 1 and 2 are connected to the positive pole 14 of the power source. The 1st output circuit part comprises TRs 22 and 23 plus resistances 24 and 25, and the 2nd output circuit part consists of TRs 26-28, diode 29 plus resistances 30 and 31. Then the base/emitter of TRs 22 and 26 is connected in parallel to the diode 21. In such constitution, the reference by which the potential is decided for two output circuits is st to the positive pole 14 and negative pole 15 respectively in order to obtain the output of opposite phase to each other against the same input. Thus the bias level of output can be stabilized for both output circuit parts by applying a DC negative feedback by the output of one side.
