Looking for documents about Distributed Amplifiers

Distributed Amplifiers

Hello,

I am looking for papers, books, thesis on Distributed Amplifiers preferably in GaAs process technology although I will take those that are in Silicon processes. I need to learn theory and application.

Thanks!

Re: Distributed Amplifiers

There is a very good book published by Artech House on this subject Fundamentals of Distributed Amplification by Thomas T. Y. Wong. The author has made such amplifiers for a reputable major company in the microwave field and writes from vast experience. One thing that is unanimously said by all of the sources on this subject I have read is that four stages is the upper limit before the imperfections in the topology limit the performance.

Re: Distributed Amplifiers

Hello,

Thank you for the recommendation.

Does this limit hold versus all process technologies ?

I have this book, and it is great, but I am looking for something more practical.
Say a thesis, paper, project or so on.

Thanks for the help though.

Re: Distributed Amplifiers

The four transistor limit was from some transistor parameter. In the days of valves/tubes the input and output capacitance was a constant value with frequency. But with semiconductors it is not. It is this non-constant loading of the line that makes the phase shift between stages different for the input line and the output line over the frequency range.
