Hi,

has anybody experience on the design and performance simulation (distortion, frequency response, stability, noise) of class-d audio power amplifiers? E.g. on hysterisis-based self-oscillating circuits vs classical pwm-based systems?
I wonder also if transient simulation is an effective method due to large simulation times and limited accuracy. I tried steady-state methods but the results are not meaningful.  I wonder if pss/qpss can be applied as succesful as in RF applications?
