Abstract
A distributed amplifier includes an input transmission circuit, an output transmission circuit, at least one cascode amplifier coupled between said input and output transmission circuits. Each cascode amplifier includes a first common-gate configured transistor coupled to the output transmission circuit, a common-source configured transistor coupled between the input transmission circuit and the common-gate configured transistor, and a second common-gate configured transistor coupled between the first common-gate configured transistor and common-source configured transistor.
