Abstract

PURPOSE:To hold the steady DC balance voltage in case the load is the inductance, by providing the feedback inverse amplifier in parallel to the transistor of the output amplifier the output load of which is the inductance and then feeding the output of the inverse amplifier back to the input side. CONSTITUTION:The signal supplied from input terminal 12 is applied to the base of TR1 of the differential amplifier possessing transistors (TR)3 and 4 of the active load, and the output of TR1 is applied to emitter-follower TR13. The output of TR13 is supplied to load inductance 18 via output TR16. Feedback circuit 27 is connected in parallel to TR16. Circuit 27 consists of feedback TR19, feedback resistances 22 and 23 plus AC bias capacity 24 each. Then the connection is secured between the base of TR19 and the base of TR16 to secure an equal potential, and thus the fluctuation is reduced for both base potentials of TR19 and TR16. In this way, the DC balance voltage can be held steadily in case load 18 is the inductance, thus securing the effective AC feedback.
