Abstract:
A distributed amplifier, comprising:an input transmission line, the input transmission line forming an input of the distributed amplifier and having a characteristic impedance associated therewith; an output transmission line, the output transmission line forming an output of the distributed amplifier and having a characteristic impedance associated therewith; and a plurality of amplifying stages arranged in a sequence and in parallel with one another, each of at least a subset of the amplifying stages including an input and an output, the input of each amplifying stage in the subset being operatively coupled to the input transmission line and the output of each amplifying stage in the subset being operatively coupled to the output transmission line, each amplifying stage in the subset having a transconductance associated therewith which is operatively configured so as to produce a gain in the amplifying stage that substantially compensates for an input signal attenuation at the respective input of the amplifying stage, at least one of the plurality of amplifying stages having a transconductance associated therewith which is greater than a transconductance associated with a preceding one of the plurality of amplifying stages in the sequence.
