| 摘要 | Various embodiments are described herein for a multi-channel class-D amplifier and an associated processing method. In general, the multi-channel class-D amplifier comprises a signal source that provides a plurality of input signals and generates synchronization information; and a plurality of class-D amplifier channel modules, each class-D amplifier channel module being configured to process a corresponding input signal from the plurality of input signals according to the synchronization information to produce an output signal. The switching frequencies employed by the plurality of class-D amplifier channel modules are substantially similar to one another and the processing of the plurality of input signals is offset in time across the plurality of class-D amplifier channel modules. | ||||||
