Abstract

Switch mode PWM amplifiers are good solutions for amplification of. Static behavioral models fail to predict the amplitude and frequency dependent phase-Gain characteristics of Class D Amplifier inside PWM modulator. Nonlinear device models are accurate but very complex and have convergence problems. Therefore there is a need to develop an accurate and time efficient behavioral model suitable for nonlinear analysis of this type of amplifier. In this paper a new behavioral model is presented which is suitable for nonlinear analysis of a Class D used in limit cycle PWM modulator. All the spectral parameters of the output of a single ended Class D are accurately predicted by this model and validated through comparison with a BSIM4 foundry device model.
