Abstract
A class D-amplifier which amplifies an input signal applied to an signal input of said amplifier () to generate an amplified signal output by an signal output () of said amplifier comprising a comparator () which compares the applied input signal with a switch signal to generate a pulse width modulated signal; a driving unit () which amplifies the pulse width modulated signal to generate the amplified output signal; and a feedback circuit which generates the self oscillating switch signal for the comparator ().
