Imaging device and electronic apparatus

Abstract

An imaging device according to the present disclosure includes a light-receiving pixel; a reference signal generator; a first amplification section; a second amplification section; a third amplification section; and a counter. The first amplification section is coupled to a first power supply node and a second power supply node. The first amplification section performs a comparison operation on the basis of a pixel signal and a reference signal. The first amplification section outputs a signal corresponding to a result of the comparison to a first node. The second amplification section includes a first transistor and a first load circuit. The first transistor includes a gate coupled to the first node, a drain coupled to a second node, and a source coupled to the second power supply node. The third amplification section includes a second transistor and a first switch. The second transistor includes a gate coupled to the second node, a source coupled to the first power supply node, and a drain coupled to a third node. The first switch applies a predetermined voltage to the third node by being turned on. The counter is coupled to a third power supply node and a fourth power supply node. The counter stops a count operation on the basis of a voltage of the third node.
