Title: Automatic gain control method and circuit applicable in burst transimpedance amplifier
Inventor: LIN SHAOHENG
IPC: H03G3/30
Filed: 2018-02-27
Abstract: Provided in the present invention is an automatic gain control method applicable in a burst transimpedance amplifier. One transistor is connected in parallel at either end of a feedback resistor of a transimpedance amplifier. A gate-source voltage of the transistor is controlled by detecting and then reversely amplifying an output voltage of the transimpedance amplifier. When an input voltage of the transimpedance amplifier is increased, the output voltage of the transimpedance amplifier is decreased, and a source electrode voltage of the transistor is subsequently decreased; when the output voltage of the transimpedance is decreased and then reversely amplified, a gate electrode voltage of the transistor is increased; this allows the gate-source voltage of the transimpedance amplifier to be increased and the transistor to be turned on; and, a portion of an input current flows through the transistor, thus reducing the current flowing through transimpedance. The present invention also provides a circuit implementing the method, obviates the need for support from any particular process, and is implementable using conventional components.
