Abstract
An amplifier circuit having a differential input and an amplifier output is provided. In some examples, the amplifier circuit includes a first input stage having a first complementary transistor pair providing a first input and a first output, the first input being a first half of the differential input; a second input stage having a second complementary transistor pair providing a second input and a second output, the second input being a second half of the differential input; an output stage coupled to the first input stage and the second input stage and providing the amplifier output; and a transistor coupled in parallel to one transistor in one of the first complementary transistor pair or the second complementary transistor pair.
