| 摘要 |
The present invention is directed toward providing a system and method of reducing RF interference in switching amplifiers without degrading performance. In one embodiment, the sampling rate of coarse high voltage modulated pulsewidths are decreased relative to the sampling rate of fine lower voltage modulated pulsewidths. This reduction in the sampling rate of coarse high voltage modulated pulsewidths results in a reduction in EMI. In addition, the higher sampling rate of the fine lower voltage modulated pulsewidths mitigates the distortion caused by the reduced sampling rate of the coarse pulsewidths. |
