摘要
A differential amplifier circuit comprising a pair of input MOS transistors, wherein inputs are supplied to the gates thereof, load circuits are connected to the drains thereof, and a current source is connected to the sources thereof, the current value of the current source is altered in line with variations in the characteristics of the input MOS transistors, thereby suppressing variations in the output level generated at the drain terminals of the input MOS transistors. In other words, unlike a conventional differential amplifier circuit, the current value of the current source is not kept to a uniform value, but rather is altered in accordance with the transistor characteristics generated by the manufacturing process.
