Abstract
The present disclosure relates to a solid state image sensor and an electronic apparatus capable of performing a gain transition at high speed. A ramp generation circuit includes sample hold circuits and ramp generation DACs, the number of which depends on kinds of required gains (for example, two kinds, i.e. a low gain and a high gain). Then, the two sample hold circuits can individually hold gain DAC output voltages at the different gains. This enables a switch to the ramp generation DAC holding the required gain voltage by means of a ramp selection signal. The present disclosure can be applied, for example, to a CMOS solid state image sensor that is used for an imaging device.
