Technical Examples

Class D amplifiers are used for their high efficiency, but they have some undesirable characteristics, one of these being the residual switching frequency ripple. Embodiments of the present invention comprise methods and apparatuses for reducing the switching frequency ripple using a technique known herein as ripple steering. A secondary output is added to the amplifier for the purpose of steering the switching ripple away from the main output thus substantially relieving the main output from a major artifact of prior art Class D amplifiers.
