Abstract (in Japanese) (See Japanese page) 
(in English) In this study, a digitally controlled variable threshold comparator is studied using stochastic A/D conversion that utilizes device mismatches. This circuit is used as a comparator in SAR-ADC and the internal DAC error is calibrated by dynamic threshold configurations. As for smaller signals than random noise, a high resolution ADC can be obtained by using stochastic A/D conversion that utilizes the statistical characteristic of the noise.
