Modulation scheme for switching amplifiers to reduce filtering requirements and crossover distortion |
摘要 |
A modulation scheme can drive an associated load that is coupled between a pair of outputs by providing a switching signal at one of the outputs and a non-switching signal at the other output independent of the direction of current relative to the respective outputs. Because switching occurs only at one of the outputs in this mode of operation, a single filter can be used to mitigate switching noise at the switching output. Another aspect relates to another mode of operation in which one or both of the outputs can be controlled to operate linearly, such as during a zero crossing condition, so as to help reduce crossover distortion.
