Efficient performance simulation of class D amplifier output stages

Nyboe, Flemming ; Risbo, Lars and Andreani, Pietro LU (2005) p.32-35
Abstract
Straightforward simulation of amplifier distortion involves transient simulation of operation on a sine wave input signal, and a subsequent FFT of the output voltage. This approach is very slow on class D amplifiers, since the switching behavior forces simulation time steps that are many orders of magnitude smaller than the duration of one period of an audio sine wave. This work presents a method of simulating the amplifier transfer characteristic using a minimum amount of simulation time, and then deriving THD from the results.
