Abstract

PURPOSE:To prevent the production of switching distortion which is observed at the class-B push-pull amplifying circuits, by avoiding the output transistor from being transferred to the cutoff region through the operation at active region. CONSTITUTION:When a signal is applied to an input terminal IN and the output point OUT is transferred to positive with the input conditions, a collector current flows to a transistor Q8, and the voltage between X and Y is kept almost the same at nonsignal. Thus, the voltage between both the bases of the 1st and 2nd transistors Q1, Q2 is increased by the voltage drop at the resistance R5, and the base voltage of a transistor Q2 to the output point OUT is kept almost the same as at nonsignal, avoiding the transistor Q2 from being transferred to the cutoff region.
