Abstract
An amplifier includes an input transistor, an input terminal, a first current source, a cascode transistor, and a second current source. The input transistor is coupled to the input terminal. The first current source is coupled to the input transistor and is configured to provide a bias current to the input transistor that is proportional to absolute temperature. The cascode transistor is coupled to the input transistor. The second current source is coupled to the cascode transistor and is configured to provide a bias current to the cascode transistor that is complementary to absolute temperature.
