发明名称 Internal all-differential operational amplifier for CMOS integrated circuits
摘要 The amplifier comprises two like CMOS cascode circuits, each having a first and a second transistors with channels having a first plurality and a third and fourth transistors with channels having the opposite polarity, the drain of the first transistor being connected to the source of the second transistor, and the drain of the fourth transistor being connected to the source of the third transistor, the drains of the second and of the third transistors being connected to each other end composing one of the output terminals of the amplifier, the sources of the first transistors being connected to each other and to the drain of a fifth transistor with a channel having the first polarity, the source of which is fed by a first supply voltage, the sources of the fourth transistors of the two cascode circuits being fed by a second supply voltage.
