Solid-state imaging device and electronic equipment

Abstract

Solid-state imaging devices and electronic equipment are disclosed. In one example, a solid-state imaging device includes a pixel array section with pixels that perform photoelectric conversion disposed in an array. A preamplifier section receives pixel signals from the pixels and a threshold signal, and amplifies their differences as differential signals. The preamplifier section is set to a shutdown state on the basis of a first control signal input. A comparator compares the differential signals with a comparison reference signal. A preamplifier through circuit includes switching elements connecting the input terminals of the preamplifier section to input terminals of the comparator section, and sets the switching elements to a connection state on the basis of a second control signal input in the shutdown state. Thus, power consumption can be reduced under conditions that allow characteristics required for the preamplifier section to be moderated.
