Abstract: The invention relates to an electronic amplifier (100) for driving a capacitive load (C), which comprises a first and a second differential input terminals (IN1, IN2) to receive an input signal (Vin), and first (OUT1) and second (OUT2) differential output terminals to provide a differential output signal (Vout). The amplifier further comprises:
- a first (101) operational device having a first (S-) and a second (S+) differential inputs connected to the first and second input terminals (IN1, IN2), respectively, and an output connected to the first output terminal (OUT1), and
- a second (102) operational device having a further first (T+) and a further second (T-) differential inputs connected to the first and second input terminals (IN1, IN2), respectively, and a further output connected to the second output terminal (OUT2). The first (101) and second (102) operational devices are operatively configured so that both the first (OUT1) and the second (OUT2) output terminals are sunk to a same reference potential (GND) during periods in which a module of differential output signal (Vout) amplitude decrease.Abstract translation: 本发明涉及一种用于驱动电容性负载（C）的电子放大器（100），其包括用于接收输入信号（Vin）的第一和第二差分输入端（IN1，IN2）和第一（OUT1）和第二 （OUT2）差分输出端子提供差分输出信号（Vout）。 放大器还包括： - 第一（101）操作装置，具有分别连接到第一和第二输入端子（IN1，IN2）的第一（S）和第二（S +）差分输入端，以及连接到 第一输出端子（OUT1）和 - 第二（102）操作装置，其具有分别连接到第一和第二输入端子（IN1，IN2）的另外的第一（T +）和另外的第二（T）差分输入，以及 连接到第二输出端（OUT2）的另一输出。 第一（101）和第二（102）操作装置可操作地构造成使得在差分输出模块的时段期间，第一（OUT1）和第二（OUT2）输出端都被吸入相同的参考电位（GND） 信号（Vout）振幅减小。
