摘要：
A liquid ejection device includes a drive waveform generator generating a drive waveform signal a modulator performing pulse modulation on a signal from the drive waveform generator to provide a modulated signal a digital power amplifier performing power amplification on the modulated signal to provide an amplified digital signal a lowpass filter smoothing the amplified digital signal to provide a drive signal of an actuator a compensator advancing the phase of the drive signal to provide a negative feedback signal and a subtractor providing a differential signal between the drive waveform signal and the negative feedback signal as an input signal to the modulator. The liquid ejection device can be used as a liquid ejection surgical instrument.
