摘要: A drive waveform signal is pulse-modulated and a modulated generated, the obtained power-amplified, then, demodulated using low pass filter. Thus negatively fed back, thereby, resonance peak of filter suppressed. In this regard, by bringing gain in wider frequency domain to take fixed value or more, having voltage exceeding power supply may be stably generated.
