Abstract
A differential amplifier circuit has a first current circuit comprising a first transistor and a second transistor, and to flow a current depending on a voltage of a first input signal, a second current circuit comprising a third transistor and a fourth transistor, and to flow a current depending on a voltage of a second input signal, a fifth transistor comprising a gate connected to a gate and the drain of the second transistor, and to flow a current that is M times greater than the current flowing between the drain and the source of the second transistor, and a sixth transistor comprising a gate connected to a gate and the drain of the fourth transistor and cascode-connected to the first transistor, and to flow a current that is N times greater than the current flowing between the drain and the source of the fourth transistor.
