Amplifier with dual current mirrors

Abstract:

An amplifier includes a first input transistor, a second input transistor, a first current mirror circuit, and a second current mirror circuit. The first input transistor is coupled to a first input terminal. The second input transistor is coupled to a second input terminal. The first current mirror circuit is coupled to the first input transistor and the second input transistor. The second current mirror circuit is coupled to the first input transistor, the second input transistor, and the first current mirror circuit.
