ABSTRACT:
An amplifier circuit includes a first transistor having a control terminal that receives a first amplifier input, a first terminal, and a second terminal. A second transistor includes a control terminal that receives a second amplifier input, a first terminal, and a second terminal that communicates with the second terminal of the first transistor. A differential transimpedance amplifier includes a first input that communicates with the first terminal of the first transistor, a second input that communicates with the first terminal of the second transistor, a first output, and a second output. A differential output amplifier includes a first input that communicates with the first output of the differential transimpedance amplifier, a second input that communicates with the second output of the differential transimpedance amplifier, a first output, and a second output.
