Abstract
An apparatus comprising an input stage, an output stage, a bias circuit and a feedback circuit. The input stage may be configured to generate a plurality of intermediate signals in response to an input signal. The output stage may be (i) DC coupled to the input stage and (ii) configured to generate an output signal in response to the intermediate signals. The output stage generally comprises a plurality of distributed amplifiers each configured to receive one of the intermediate signals. The bias circuit may be (i) connected between the input stage and the output stage and (ii) configured to adjust an input impedance of the input stage.
