Abstract
An object of the invention is to reduce an offset voltage to realize a small occupying area in a comparator using MOS type transistors. The invention is characterized in that impurities are introduced into channel areas of MOS type transistors, and mobility of the MOS type transistor on a load side is smaller than mobility of the MOS type transistor on a differential side, and a mutual conductance gm of the MOS type transistor on the load side is smaller than a mutual conductance gm of the MOS type transistor on the differential side.
