A COMPENSATION DEVICE USING CHARGE SHARING

摘要

PURPOSE: A compensation device using a charge sharing method removes a compensation circuit connection pin by integrating a capacitor of a compensation device into a chip with a stable method. CONSTITUTION: A first amplifier (100) receives a reference voltage and a comparison voltage and outputs the same to an output terminal. One side of a first switch unit (200) is connected to the output terminal of the first amplifier. One side of a second capacitor unit (300) is connected to the other side of the switch unit. One side of a first capacitor (500) is connected to the output terminal of the first amplifier. One side of a second switch unit (600) is connected to the other side of the first capacitor. One side of a third capacitor (800) is connected to the other side of the second switch unit. The other sides of the second capacitor unit and the third capacitor are connected to a ground voltage and integrated on one chip.
