Title: ANALOG-DIGITAL CONVERTER, SOLID-STATE IMAGING ELEMENT, AND ELECTRONIC DEVICE
Abstract:
The present invention is provided with an integration circuit unit that integrates the difference between the value of an analog input signal and a feedback value, a quantization circuit unit that converts the output of the integration circuit unit to a digital value, a first current-steering digital-analog conversion unit that generates the feedback value in accordance with the output of the quantization circuit unit, and a second current-steering digital-analog conversion unit that is different from the first current-steering digital-analog conversion unit. The output end of the first current-steering digital-analog conversion unit or the second current-steering digital-analog conversion unit is connected to the input end of the integration circuit unit.
