PROBLEM TO BE SOLVED: To provide a quantizer, a comparison circuit and a semiconductor integrated circuit that perform a normal operation by shortening the time for which a through current flows through the quantizer.SOLUTION: A quantizer 12 for receiving an analog signal Q and outputting a binary signal SS includes through current detection sections M1, M2 for detecting a through current flowing through the quantizer, and feedback sections M5-M7, M8-M10 for feeding back a signal from the through current detection section to control a charge of an input N1 of the quantizer. |
