CPC H01L 27/14643 (2013.01) [H01L 27/14609 (2013.01); H03M 1/12 (2013.01); H04N 25/60 (2023.01); H04N 25/75 (2023.01)] | 16 Claims |
1. A photoelectric conversion device comprising:
a light receiving circuit configured to convert light into an electrical signal;
a first hold circuit configured to hold a data signal which represents the electrical signal converted from the light;
a second hold circuit configured to hold a noise signal read out from the light receiving circuit in a reset state;
a first resistive element to which a voltage corresponding to a difference between the data signal held by the first hold circuit and the noise signal held by the second hold circuit is applied;
an analog-to-digital (A/D) converter configured to convert an analog current flowing in the first resistive element into digital data;
a second resistive element; and
a temperature detection circuit configured to generate, based on a current flowing in the second resistive element, an analog output corresponding to an internal temperature of the photoelectric conversion device.
