}As openand closed-loop Class-D amplifiers increasingly become the preferred choice of consumer-audio electronics designers, a different way of looking at the effects of power-supply ripple is needed to adequately capture the performance of the amplifier. Today’s audio designers are increasingly focused on reducing system cost, shrinking form factors and delivering high-quality audio, all of which require high supply-noise rejection architectures. Unfortunately, the power-supply rejection ratio… CONTINUE READING
