Abstract

PURPOSE: To shorten a stabilization time when a power source is put to work, by short-circuiting the negative feedback resistance of a negative feedback amplifier right after the power source is put to work.
CONSTITUTION: The output of a signal source 1 is supplied to a negative feedback amplifier 2. The low-frequency-range characteristics and amplification factor are determined by resistances 5 and 6 and a capacitor 7. A signal processing circuit 3 outputs a detection signal in response to an input exceeding a threshold level. A switching means 4 short-circuits a negative feedback resistance 5 by the detection signal of the circuit 3. When a power source is put to work, the input of the amplifier 2 is unbalanced, so the resistance 5 is short-circuited by the switching means 4. At this time, the capacitor 7 is charged through only the resistance 6, shortening the charging time.
