  • Quenching circuit
    Patent number: 10312382
    Abstract: Disclosed is a quenching circuit including an avalanche photodiode and a quenching diode applying a bias voltage to the avalanche photodiode. Since the quenching circuit includes the quenching diode instead of a quenching resistor, the avalanche photodiode can quickly recover to linear mode from Geiger mode, and the bias voltage applied to the avalanche photodiode is stably maintained even though a current level of the avalanche photodiode fluctuates according to the intensity of incident light.
    Type: Grant
    Filed: March 21, 2018
    Date of Patent: June 4, 2019
    Assignee: Hongik University Industry-Academia Cooperation Foundation
