Abstract
There is provided a liquid discharging apparatus including: a modulation portion which generates a modulation signal pulse-modulated from a source signal; a gate driver which generates an amplification control signal based on the modulation signal; a transistor which generates an amplification modulation signal amplified from the modulation signal based on the amplification control signal; a low pass filter which demodulates the amplification modulation signal and generates a driving signal; a feedback circuit which sends back the driving signal to the modulation portion; a boosting circuit which supplies a voltage which has been boosted based on any one of a first clock signal and a second clock signal to the gate driver; a boosting control portion which controls boosting in the boosting circuit; and a piezoelectric element which is displaced as the driving signal is applied.
