Title:
PHOTODETECTOR AND DISTANCE MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/202451
Kind Code:
A1
Abstract:
A photodetector (1) is provided with a plurality of pixel circuits (11). Each pixel circuit (11) is provided with a SPAD (1d) and a first element that is a variable resistor or switch having one end connected to one end of the SPAD (1d). The other ends of the plurality of first elements are connected in parallel. The other ends of the plurality of SPADs (1d) are connected in parallel, and the other ends connected in parallel are connected to a second resistor (R2). The resistance value R2 of the second resistor (R2) is higher than the resistance value R1 of a resistance component at the other end of the first element.
