Abstract

This paper describes the application of the feedforward linearization technique to a distributed amplifier. The circuit architecture of the distributed amplifier is used in a new way to simplify the feedforward system's configuration. A distributed amplifier using a pseudomorphic HEMT with feedforward linearization based on the new concept is simulated to evaluate the performance and demonstrate the feasibility of achieving broadband linearity. The experimental results for an MIC implementation are also presented as proof of the concept. © 2005 Wiley Periodicals, Inc.

This paper presents a power series approach to accurately obtain the damped separatrices for a class of unforced non-linear oscillators. This in turn delineates the basins of attraction of two or more stable attractors in the phase space. The method is illustrated by its applications to the unforced
