Abstract:
A method of arranging a capacitor array of a successive approximation register analog-to-digital converter in a successive approximation process, the method including: splitting a binary capacitor array into unit capacitors, then sorting, grouping, and rotating the original binary capacitive array involved in successive approximation conversion.
