摘要：
A reference voltage generating circuit includes: a first capacitor; a second capacitor; a reference voltage sampling capacitor; a first switch for alternatively coupling the second capacitor to a predetermined voltage to allow the second capacitor to sample the predetermined voltage; a second switch for alternatively coupling the second capacitor to the first capacitor to allow the second capacitor to redistribute charges with the first capacitor in order to generate the reference voltage; and a third switch for alternatively coupling the first capacitor to the reference voltage sampling capacitor to allow the reference voltage sampling capacitor to redistribute charges with the first capacitor in order to output the reference voltage.
