High-frequency piezo amplifier driver - EDN
https://www.edn.com/high-frequency-piezo-amplifier-driver/
For a high-frequency piezoelectric actuator whose capacitance is 1.1uF, the required peak voltage is 30V, and the driving frequency is 15kHz; the peak current required from the driver is about 2.5A (5.0A peak-to-peak). The piezo driver must be able to output such high current, high voltage, and high frequency at the same time.
