An amplifier circuit includes a first amplifier having an input and an
output, and a second amplifier having an input that communicates with the
output of the first amplifier, and an output. The amplifier circuit
includes a first capacitance that communicates with the input of the
first amplifier and the output of the second amplifier. The amplifier
circuit includes a third amplifier having an input that communicates with
the output of the second amplifier, and an output. The amplifier circuit
includes a second capacitance that communicates with the output of the
third amplifier and the input of the second amplifier.
