ANALOG-TO-DIGITAL SIGNAL CONVERSION SYSTEM AND METHOD

WIPO Patent Application WO/2019/071371

A1

An analog-to-digital signal conversion system (300) and method. The system (300) comprises a digital signal splitting unit (401), a first digital signal storage unit (411), a second digital signal storage unit (421), a first storage capacitance selection unit (412) and a second storage capacitance selection unit (422), wherein the digital signal splitting unit (401) is used for splitting a signal code N of a digital control signal into a first signal code K represented by a number of bits x and a second signal code P represented by a number of bits y, said signal code N being output and fed back by the analog-to-digital signal conversion system (300) and being represented by a number of bits z; the first and second digital signal storage units (411, 421) are respectively used for sequentially storing the first signal code K and the second signal code P; and the first and second storage capacitance selection units (412, 422) are respectively used for selecting the storage capacitances of the first signal code K and the second signal code P. Therefore, the number of leads and the amount of hardware inside a system is greatly decreased, power consumption is reduced, and the overall operational efficiency of the system is improved.
