Abstract (in Japanese) (See Japanese page) 
(in English) This study investigated the noise suppression effect of multiple sampling applied to a 3-stage pipeline analog-to-digital converter (ADC) in a 33-megapixel, 120-fps 1.25-in CMOS image sensor. The 3-stage pipeline ADC is composed of folding-integration (FI), cyclic, and successive approximation register ADCs, and the multiple sampling for noise suppression is implemented in the FI ADC. The sampling number M is limited by the conversion interval of the FI ADC and the maximum sampling number is M = 6 at the 120-fps operation. To investigate the noise suppression effect of 120-fps operation, we measured the random noise of the pixel readout circuit to the sampling number M and compared with theoretical calculations. As a result, we confirmed that the measurement result corresponds reasonably well with the calculated result and the sampling number M = 6 is effective for noise suppression. Furthermore, the calculations revealed that the influence of 1/f noise of the source follower is dominant on the noise performance.
