The low noise amplifier (LNA) is a significant device in RF front-end. In this paper, a straight and efficient modeling method for LNA based on the Volterra series with recursive least squares (RLS) algorithm is proposed. Instead of calculating the high nonlinearity order of Volterra kernels, the proposed method extracts the first three order Volterra kernels characterizing the memory effect to construct...
A simple and quick model is explored to analyze the radiation of the pigtail-terminated coaxial cable in this paper. Unexpected radiated electromagnetic interference is produced due to the pigtail and influences the surrounding equipment. To study the mechanism of the pigtail effect, the actual pigtail connection is modeled as two transmission lines cascade connection. The currents on the transmission...
