Patent JP-H01220506-A (JP)
Title: Amplifier
Inventor: HAYASHI SHIGERO
IPC: H03F3/347
Filed: 1988-02-27
Abstract: PURPOSE:To set the bias level of a circuit at a succeeding stage without wiring a signal line by inputting a signal from the base of a transistors on one side of two transistors whose collectors are connected, and controlling the base voltage of the transistor on the other side by an external control signal. CONSTITUTION:A DC amplifier D is provided with three bipolar type transistors(TR) C, E, and F and two resistors. The TrC inputs, for example, the signal from a photodetector to its base, and outputs the signal after amplification from its collector via the resistor R1. The TrE controls the emitter voltage of the TrF corresponding to its base voltage. A monitor circuit 12 differentiates 12A the AC component of a differential amplifier 11, and integrates 128 it, and compares it with a preset value, and supplies the base voltage to the TrE so as to eliminate a difference. Then, the voltage between the base and the emitter of the TrF changes, thereby, a bias voltage at the comparison input terminal of the amplifier 11 can be kept constant.
