Start up noise in a class D amplifier--is corrected by adding an analog switch S1 to the integrator circuit A1. A resistor R3 in the feedback path of A1 prevents A1 from saturating. In an alternate embodiment silent start switch connects a variable resistance to the comparator input. The resistance gradually increases.
