Abstract
The present disclosure relates to an analog-to-digital conversion circuit comprising: N sampling and conversion modules connected in parallel, configured to simultaneously sample and sequentially convert first analog signals of N channels to output second analog signals, wherein each of the sampling and conversion modules includes a plurality of sampling capacitors connected in parallel, wherein N is an integer greater than 1; a comparator connected to the N sampling and conversion modules, configured to comparing the second analog signals respectively to obtain comparison signals; and a control module connected to the N sampling and conversion modules and the comparator, configured to control the N sampling and conversion modules to output converted digital signals based on the comparison signals.
