Patent ID: 7525385

Claim:
A traveling wave amplifier, comprising: an input port adapted to receive a signal to be amplified; an output port adapted to output an amplified signal; and a plurality of stages provided between the input port and the output port, each stage including: an input path including a first input oath terminal and a second input path terminal; an output path including a first output path terminal and a second output path terminal; a first field effect transistor having a gate connected to the input path between the first input path terminal and the second input path terminal, a drain connected to a supply voltage, and a source; a second field effect transistor having a gate connected to the source of the first transistor, a source connected to a second supply voltage, and a drain; and a third field effect transistor having a pate connected to a bias voltage, a source connected to the drain of the second transistor, and a drain connected to the output path between the first output path terminal and the second output path terminal; a parallel resistor/capacitor (RC) circuit connecting the source of the second transistor to the second supply voltage.
