Abstract

An amplifier arrangement has a first differential stage with a first transistor pair, a second differential stage with a first and a second transistor pair, each pair having a common source connection coupled to a drain terminal to a respective one of the transistors of the first differential stage. The amplifier arrangement further has a first complementary differential stage with a transistor pair having opposite conductivity type compared to the transistor pair of the first differential stage, and a second complementary differential stage with a first and a second transistor pair of the complementary conductivity type. The first and the second complementary differential stage are connected symmetrically compared to the first and the second differential stage. The transistors of the second complementary differential stage are symmetrically connected to the transistors of the second differential stage such that respective first, second, third and fourth current paths are formed. A pair of output terminals is coupled to the first and the second current path. Gate terminals of the transistors of each of the stages are coupled to a respective pair of input terminals.
