Abstract
The present invention discloses a successive approximation analog-to-digital converter, comprising: a capacitor array including a designated capacitor and several sampling capacitors to sample an input signal under a sampling mode; a comparator to compare a first voltage from the capacitor array with a second voltage under a comparison mode and thereby generate a comparison result; a switching circuit to determine the charge amount stored in the capacitor array under the sampling mode and the first voltage under the comparison mode according to a control signal; and a control circuit to generate the control signal according to a sampling setting under the sampling mode and generate the control signal according to the comparison result under the comparison mode. Said designated capacitor does no sampling under the sampling mode, but appropriates the charges of the sampling capacitors under the comparison mode, so as to reduce the effective sampling value.
