Title:
SOLID-STATE IMAGING ELEMENT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/073705
Kind Code:
A1
Abstract:
The present invention makes excess bias an appropriate value in a device for detecting light. This solid-state imaging element is provided with a photodiode, resistor, and control circuit. In this solid-state imaging element, the photodiode subjects incident light to photoelectric conversion and outputs a photocurrent. Further, in the solid-state imaging element, the resistor is connected to the cathode of the photodiode. Additionally, in the solid-state imaging element, the higher the potential of the cathode when the photocurrent flows into the resistor, the lower the potential that the control circuit supplies to the anode of the photodiode.
