Patent ID: 8058930

Claim:
A non-uniformly distributed amplifier (NDA) comprising: a plurality of amplifier segments, such that each of the plurality of amplifier segments has an input gate and an output drain; a first plurality of inductive elements coupled in series between an NDA 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 and is associated with a corresponding one of a plurality of capacitive elements that is coupled between each of the first plurality of connection nodes and a corresponding input gate of the plurality of amplifier segments; an input network comprising the plurality of capacitive elements, such that a capacitance of each of the plurality of capacitive elements decreases moving from the NDA input to the first output to compensate for varying phase velocity along the second plurality of inductive elements; and a second plurality of inductive elements coupled in series between a first input and an NDA 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 segments; and an inductance of each of the second plurality of inductive elements decreases moving from the first input to the NDA output to compensate for decreasing impedance along the second plurality of inductive elements.
