ABSTRACT:
A semiconductor differential amplifier includes first and second MOS transistors of a first conductivity type acting as driver transistors, and third through sixth MOS transistors of a second conductivity type acting as load transistors. First and second input terminals are respectively connected to gate terminals of the first and fifth, and second and sixth transistors. Therefore, since input signals are applied to transistors of both the load and driver sections of the amplifier, the amplifier exhibits a higher sensitivity for detecting relatively small differences between the voltage at the first input terminal and the voltage at the second input terminal.
