Title:
SOLID-STATE IMAGING ELEMENT, ELECTRONIC DEVICE AND CONTROL METHOD FOR SOLID-STATE IMAGING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2017/179319
Kind Code:
A1
Abstract:
The present invention prevents the occurrence of a black spot phenomenon in a differential amplification-type solid-state imaging element. A signal-side amplification transistor supplies a signal current corresponding to one of a pair of differential input voltages from an output node to a common mode node to generate an output voltage corresponding to the signal current. A reference-side amplification transistor supplies a reference current corresponding to the other of the pair of differential input voltages to the common mode node. A constant current source controls the sum of the signal current and the reference current that join at the common mode node to be constant. A bypass control unit connects the output node and the common mode node if the output voltage reaches a predetermined limited voltage, and supplies the signal current having a value corresponding to the limited voltage to the common mode node.
