Patent ID: 7898334

Claim:
An amplifier circuit comprising: an amplifier including an inverting input that is directly connected to an input signal, a non-inverting input, and an output; a first feedback path that is directly connected to the inverting input and the output of the amplifier; a second feedback path that is directly connected to the inverting input and the output of the amplifier, wherein the first feedback path provides feedback at a lower frequency than the second feedback path; a first resistance, wherein a first end of the first resistance communicates with the output of the amplifier; a first capacitance, wherein a first end of the first capacitance communicates with a second end of the first resistance; and a second resistance, wherein a first end of the second resistance communicates with the inverting input, wherein a second end of the second resistance communicates with the second end of the first resistance, wherein the first feedback path includes a third resistance in series with a second capacitance, wherein the second feedback path includes a third capacitance, and wherein the second capacitance has a first capacitance value that is substantially greater than a second capacitance value of the third capacitance.
