Abstract
A distributed amplifier (DA) is disclosed. The DA includes a first plurality of inductive elements coupled in series forming a first plurality of connection nodes. The DA also includes a second plurality of inductive elements coupled in series forming a second plurality of connection nodes. The DA further includes a plurality of amplifier cells that each has a main transistor and a cascode transistor coupled into a cascode configuration. The cascode transistor has a current input coupled to a corresponding one of the first plurality of connection nodes. An input transistor has a control terminal coupled to a corresponding one of the second plurality of connection nodes, a current input terminal configured to provide a bias tuning for the DA, and a third current output terminal coupled to a control terminal of the main transistor and configured to provide a separate bias tuning for the DA.
