Integrated circuit amplifiers.

摘要

In a Class B integrated circuit amplifier having a complementary symmetry emitter follower-type output stage, an NPN transistor (Q5) is connected effectively in parallel with the PNP output transistor (Q4) and is arranged to draw a current dependent upon the current flowing in the emitter-collector path of the PNP transistor (Q4), to compensate for the relatively poor characteristics of the PNP transistor (4). <IMAGE>
