Abstract
A binarization circuit includes a comparator that outputs a signal according to a differential voltage between the input and reference voltages. The first charging-discharging circuit generates a first voltage. The second charging-discharging circuit generates a second voltage. The control circuit compares the differential voltage with the threshold voltage, and switches between turn-on and turn-off of the second charging-discharging circuit based on a difference between the differential voltage and the threshold voltage. A sum of the reference and first voltages of the preceding clock is supplied to the comparator when the second charging-discharging circuit is turned off. A sum of the reference and the first and second voltages of the preceding clock is supplied to the comparator when the second charging-discharging circuit is turned on.
