New design of flat gain and wideband field effect structure

Abstract

This paper provides a new possibility of realizing in chip form wideband amplifiers with simple wide gate field effect structures, by taking advantage of especially designed electrode terminations to overcome inherent traveling wave losses. Demonstration of these properties is performed through various realizations and is based on distributed equivalent circuit modelling.

Modeling and Optimization of Traveling Wave Field Effect Transistors

“…This has been proposed in a previous paper [6] and consists of using additional pads at the electrode ends and suitable onchip terminal impedances. Work reported is essentially experimental but provides analysis and optimization considerations based on a simulation using a distributed equivalent circuit analysed with the SPICE software.…”
