Abstract
An electronic amplifier for driving a capacitive load may include first and second differential input terminals to receive an input signal, and first and second differential output terminals to provide a differential output signal. The amplifier may further include a first operational device having first and second differential inputs connected to the first and second differential input terminals, respectively, and an output connected to the first differential output terminal, and a second operational device having first and second differential inputs connected to the first and second differential input terminals, respectively, and an output connected to the second differential output terminal. The first and second operational devices may be operatively configured so that both the first and the second output terminals are at a same reference potential during periods in which a magnitude of differential output signal amplitude decreases.
