摘要： Operation of a digital power amplifier for power amplification of a modulated signal is stopped in a period in which a voltage value of a drive signal applied to a capacitive load is constant, to thereby suppress power loss. The power amplification is stopped either when half a period of time when the modulated signal in a first voltage state maintains the first voltage state elapses or when half a period of time when the modulated signal in a second voltage state which is lower in voltage than the first voltage state maintains the second voltage state elapses. Accordingly, when electric current does not flow in a inductor of a low pass filter, it is possible to stop the power amplification. Thus, it is possible to prevent generation of voltage fluctuation in the drive signal due to an electromotive force caused by a self-induction phenomenon of the inductor.
摘要翻译：在施加到电容性负载的驱动信号的电压值恒定的时段内停止用于调制信号的功率放大的数字功率放大器的操作，从而抑制功率损耗。当第一电压状态下的调制信号保持第一电压状态或当电压低于第二电压状态的第二电压状态的调制信号的半个时间段的半个时间段停止功率放大，第一电压状态保持第二电压状态已经过去。因此，当电流不在低通滤波器的电感器中流动时，可以停止功率放大。因此，可以防止由电感器的自感现象引起的电动势引起的驱动信号中的电压波动的产生。
