具有减少的EMI生成的高效D类放大器
摘要：
一种D类放大器包括信号处理组块。信号处理组块当第一差分信号的占空比大于第二差分信号的占空比时生成表示第一差分信号与第二差分信号之间差值的第一已处理信号。信号处理组块当第一差分信号的占空比小于第二差分信号的占空比时生成表示参考DC电平的第一已处理信号。当第二差分信号的占空比大于第一差分信号的占空比时生成表示第二差分信号与第一差分信号之间差值的第二已处理信号，以及当第二差分信号的占空比小于第一差分信号的占空比时生成表示参考DC电平的第二已处理信号。
摘要（英）：

A Class D amplifier includes a signal processing block. The signal processing block generates a first processed signal representing a difference between the first differential signal and the second differential signal when a duty cycle of the first differential signal is greater than a duty cycle of the second differential signal. The signal processing block generates a first processed signal representing a reference DC level when the duty cycle of the first differential signal is less than the duty cycle of the second differential signal. A second processed signal representing the differencebetween the second differential signal and the first differential signal is generated when the duty cycle of the second differential signal is greater than the duty cycle of the first differential signal, and a second processed signal representing the reference DC level is generated when the duty cycle of the second differential signal is less than the duty cycle of the first differential signal.
