Title: PWM in negative feedback loop
Post by Prabhu on Sep 13^th, 2007, 4:27am

Hi,

What determines the UGB of the integrator in a closed loop PWM class D amplifier, apart from reducing the openloop non-linearities ( deadtime, psrr etc)?
How is it related to the suppression of the highfrequency intermodulation components aliasing back to the output?

Thanks,
Raja
