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 fluid ejection device configured to eject fluid from an ejection port includes a driving element that pressurizes the fluid and causes it to be ejected from the ejection port by being driven according to a voltage applied thereto. A driving voltage waveform selecting unit selects a driving voltage waveform to be applied to the driving element from among a plurality of types of the stored driving voltage waveforms. Power sources set the voltage to be outputted. A power source voltage determining unit determines voltages to be set to the power sources on the basis of the selected driving voltage waveform. A driving voltage waveform applying unit applies the selected driving voltage waveform to the driving element by setting the determined voltages to the power sources and connecting the power sources to the driving element while switching the same.
