摘要： PROBLEM TO BE SOLVED: To accelerate switching of gain setting by shortening settling time.SOLUTION: By a DA converter, a plurality of gain setting values are set with respect to a plurality of cascode transistor groups, a predetermined gain setting value out of the plurality of gain setting values is set with respect to a current source transistor group, the cascode transistor group is selected in which the same gain setting value as that set with respect to the current source transistor group is set, and an output current outputted by the current source transistor group connected to the selected cascode transistor group is outputted after current-voltage conversion. This technology can be applied to, for example, a solid state imaging element or the like.
