Abstract
An offset correcting circuit includes: an amplifying unit including an offset adjusting unit that adjusts an offset of the amplifying unit; and an offset determining unit that outputs a signal to detect and corrects the offset of the amplifying unit. The offset determining unit includes a comparing unit that compares an output of the amplifying unit with a reference value, and a counter that increases or decreases a count value in response to an output of the comparing unit. The offset adjusting unit adjusts the offset based on the count value.
