The present disclosure relates to a solid-state imaging device and an electronic apparatus that are capable of suppressing reduction in sensitivity. A current comparison unit receives light incident on a pixel, performs photoelectric conversion to generate a voltage, compares a current generated from the voltage with reference to a first potential line and a reference current generated with reference to a second potential line, the first potential line being one of a power supply line and a grounding line, the second potential line being another one of the power supply line and the grounding line, and outputs a comparison. A feedback unit returns a signal to a source side in the current comparison unit when the current is generated, the signal using the comparison result by the current comparison unit. The feedback unit can perform standby control in the current comparison unit.
