Stability analysis of a class A four stages Williamson amplifier with feedback applied

12 Credits

Description

Method to estimate the stability phase margin of a tube amplifier with feedback applied using the SPICE simulation, with the approximation of the linearization of the final tubes KT88 approximated to piecewise linear devices. Ultralinear transformer. Power supply rectifier with tubes diodes 5U4, Ia-Va characteristic of KT88 in ultralinear mode 42%, Analysis of gain versus frequency, amount of feedback and its influence on damping factor.
