    Abstract: A solid-state imaging device includes a pixel array with unit pixels each having a photoelectric conversion device arranged in a matrix. Column signal lines are wired with respect to one column in the pixel arrangement and pixels are regularly connected to the column signal lines in accordance with rows in which pixels are positioned. A pixel signal reading unit has a column processing unit that reads pixel signals in units of plural pixels from the pixel array and performs column processing to read signals on a column basis, wherein the pixel signal reading unit includes a column input unit which can connect one or plural column signal lines arranged at a corresponding column to an input of one column processing unit through plural capacitors connected in parallel The column input unit has switches which can change a connection state between capacitors and column signal lines corresponding to the column.

    Abstract: The present technology relates to an image sensor, an electronic apparatus, a comparator, and a drive method enabling achievement of a noise reduction while maintaining high speed of AD conversion. An ADC for performing AD conversion for an electrical signal output from a pixel includes a comparator that compares the electrical signal and a reference signal, a level of which is changed and a counter that counts time necessary for a change of the reference signal to a coincidence of the electrical signal and the reference signal on the basis of output signals from the comparator. The comparator includes a differential amplifier that outputs a comparison result signal indicating a comparison result obtained by comparing the electrical signal and the reference signal and a plurality of output amplifiers that outputs signals obtained by amplifying the comparison result signal output from the differential amplifier as the output signals at different timings.
