  • Patent number: 7683720
    Abstract: A system and method are provided for a folded cascode amplifier circuit that includes a first order high-pass filter coupled to a first bias voltage, a first input signal and a second input signal, the first input signal and the second input signal defining a differential input signal and the first order high-pass filter arranged to establish a first bias output and a second bias output. To amplify the full-spectrum content of the input signal, the amplifier circuit includes a full-spectrum content amplifier coupled between the first input signal, the second input signal and a current source. To amplify the high-frequency content of the input signal to achieve equalization, the amplifier circuit includes a high-frequency content amplifier coupled to the first bias output and the second bias output, the high-frequency content amplifier arranged to amplify the high-frequency content of the differential input signal to achieve equalization.
