A Uniform Approach to Distortion Analysis
An analysis of feedback amplifiers is presented which clearly shows the fundamental similarity that exists between the major identifiable types of distortion, such as THD, SID, etc. By viewing distortion as a dependent input noise source and using network transformations a simple cascade model is introduced which puts most forms of distortion in an elegantly simple common perspective. General equations for distortion are derived from the model and applied to a few typical circuit configurations.
