    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： A modulated signal is generated by performing pulse modulation of a drive waveform signal that is a reference for a drive signal to be applied to a capacitive load, and the drive signal is generated by performing power amplification of the acquired modulated signal and then smoothing the power-amplified modulated signal. Then, negative feedback of the drive signal applied to the capacitive load is applied to the drive waveform signal that is the reference for the drive signal. At this time, a predetermined analog compensation process for smoothing gain characteristics in a frequency band included in the drive signal is performed for the drive signal, then the acquired signal is converted into a digital signal, and negative feedback of the digital signal is applied to the drive waveform signal.

    摘要： A driving device of a capacitive load includes a modulator that executes pulse modulation on a drive waveform signal. An inductor performs low-pass filtering on the modulated drive waveform signal and outputs the low-pass filtered signal as a drive signal towards a load capacitor as the capacitive load. A load selection control circuit selects a load capacitor and a dummy load capacitor to be connected to the inductor so that a sum of the capacitances of the selected load capacitor and dummy load capacitor is kept within a predetermined range. A feedback circuit executes a filtering process on the drive signal so that a frequency characteristic of a passing band of the drive signal becomes substantially flat. The resulting signal is provided to the modulator as a feedback signal. The modulator executes the pulse modulation on a difference value between the drive waveform signal and the feedback signal.
