The system includes a power supply, a SPAD, a control circuit and a load. The power supply generates a supply voltage. The SPAD has a first terminal receiving the supply voltage and a second terminal generating an output voltage signal. The control circuit is connected to the second terminal of the SPAD. The load has a first terminal connected to the second terminal of the SPAD, and a second terminal connected to the control circuit for receiving a reset level. The control circuit is capable of monitoring a swing of the output voltage level and generating the reset level in response to the excess bias level and the swing of the output voltage level."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for controlling excess bias of single photon avalanche photo diode","description":"A system for controlling excess bias of a single photon avalanche photo diode (SPAD) is provided.
