Patent ID: 7397306

Claim:
An amplifier circuit, comprising: a first transistor having a control terminal that receives a first amplifier input, a first terminal, and a second terminal; a second transistor having a control terminal that receives a second amplifier input, a first terminal, and a second terminal that communicates with said second terminal of said first transistor; a differential transimpedance amplifier having a first input that communicates with said first terminal of said first transistor, a second input that communicates with said first terminal of said second transistor, a first output, and a second output; and a differential output amplifier comprising at least one of a differential operational amplifier, a differential telescopic cascoded amplifier and a differential push-pull amplifier and having a first input that communicates with said first output of said differential transimpedance amplifier, a second input that communicates with said second output of said differential transimpedance amplifier, a first output, and a second output.
