Patent ID: 8665022

Claim:
A distributed amplifier (DA) comprising: a plurality of amplifier sections, such that each of the plurality of amplifier sections has an input gate and an output drain; a first plurality of inductive elements coupled in series between a DA input and a first output to form a first plurality of connection nodes, such that each of the first plurality of connection nodes is coupled to a corresponding adjacent pair of the first plurality of inductive elements; a second plurality of inductive elements coupled in series between a first input and a DA output to form a second plurality of connection nodes, such that each of the second plurality of connection nodes is coupled to a corresponding adjacent pair of the second plurality of inductive elements and to a corresponding output drain of the plurality of amplifier sections; and an active impedance termination circuit having a termination input coupled to the first output and a termination output coupled to one of the second plurality of connection nodes adjacent to the DA output.
