Distributed amplifiers with embedded signal shaping for multigigabit transmission systems

Abstract

This paper discusses the use of distributed amplifiers as transversal filters for high bit rate pulse shaping/filtering applications. Two schemes demonstrating a general approach, obtained by optimising one or more transversal filter parameters are explored. Simulation results, based on the parameters of a commercially available 40 GHz HEMT foundry process, are presented to illustrate the practicability of the different schemes.
