Abstract
PURPOSE: To increase the range in which an amplifier works in a normal way, by approximating the protecting line to the ASO line.
CONSTITUTION: A voltage dividing circuit in which the resistances 27, 28 and 29 are connected in series is provided between the power sources +B and -B, and the connection points 30 and 31 among the rsistances are used for the partial pressure output terminals. Tha bases of the transistors 15 and 16 are connected to the partial pressure output terminal 31 via a serial circuit of the resistance 23 and diode 25 plus a serial circuit of the resistance 24 and diode 26. At the same time, the said bases are connected to the partial pressure output terminal 30 via a serial circuit of the resistance 19 and diode 21 plus a serial circuit of the resistance 20 and diode 22, and furthermore connected to the sources -B and +B via the resistances 17 and 18. In such constitution, two folded points are produced to the protecting line C. As a result, the line C can be approximated to the ASO line A more accurately.
