An apparatus comprising an input stage (102), an output stage (104), a bias circuit (106) and a feedback circuit. The input stage (102) may be configured to generate a plurality of intermediate signals in response to an input signal. The output stage (104) may be DC coupled to the input stage; and configured to generate an output signal in response to the intermediate signals. The output stage (104) generally comprises a plurality of distributed amplifiers each configured to receive one of the intermediate signals. The bias circuit (106) may be connected between the input stage (102) and the output stage (104); and configured to adjust an input impedance of the input stage. |
