Design a distributed amplifier system using II-filtering structure

Abstract EN

This paper reviews in brief the principle of distributed amplifier with its classical structure.

Alternation to the basic design including the use of π-filtering sections instead of T-sections in gate and drain lines is proposed.

The new design method has the advantages of much gain flatness near the cutoff frequency and less inductances at the corners of the amplifier.

These are great benefits make the new design to be better than the previous ones especially in modeling the amplifier in integrated circuit technology.

The distributed amplifier is used in microwave applications.
