Abstract

PURPOSE: To simplify the circuit, by common use of a resistor of a feedback circuit and a bias circuit.
CONSTITUTION: A power supply 7 is connected to a collector of a transistor (TR)6. The base bias voltage of the TR6 is given via resistors 9a, 9b from the collector. A feedback signal from the collector is given to the base via the resistor 9a and a capacitor 4. Since a resistor constituting a voltage division circuit to obtain the base bias voltage has greater resistance than the resistor in a feedback circuit, a feedbakc signal in AC is picked up at a capacitor 4 from a dividing point by the resistors 9a, 9b.
