An amplifier system includes a first amplifier stage having an input and an output. A second amplifier stage has an input and an output, the input of the second amplifier stage being connected to the output of the first amplifier stage. A transistor has a control terminal, a first terminal, and a second terminal, the first terminal of the transistor being coupled to the output of the first amplifier stage and the input of the second amplifier stage. A first capacitance has a first terminal and a second terminal, the first terminal of the first capacitance being connected to the input of the first amplifier stage, the second terminal of the first capacitance being connected to the second terminal of the transistor. A first current source to source current to amplifier system, the first current source being is connected to the output of the first amplifier stage. A second current source will sink current from the amplifier system. The second current source is connected to the second terminal of the first capacitance and the second terminal of the transistor.
