Original Abstract Submitted

The present disclosure provides a successive comparison type A/D converter. The successive comparison type A/D converter includes a D/A converter, configured to generate an analog output voltage according to a digital input; a comparator, configured to compare a voltage according to an analog input signal with an output voltage of the D/A converter; and a control circuit, configured to input the digital input to the D/A converter. The D/A converter includes: a capacitive D/A conversion circuit, including an output line connected to the comparator and a plurality of capacitors respectively connected to the output line; an isolation capacitor, connected to the output line; and a current source. The current source is configured to output a current signal to the output line through the isolation capacitor in synchronization with an input of the digital input to the D/A converter by the control circuit.
