ABSTRACT:
An amplifier system includes a first amplifier, a second amplifier, a first capacitance, and a first transistor. The first amplifier has an input and an output. The second amplifier has an input that communicates with the output of the first amplifier. The first capacitance has one end that communicates with the input of the first amplifier. The first transistor has a control terminal, a first terminal that communicates with the output of the first amplifier, and a second terminal that communicates with another end of the first capacitance.
