Therein the shaper circuit is configured to provide an output signal (Vout) as a function of the input signal (Iin), the output signal (Vout) comprising one or more voltage pulses, and the RC component (40) is configured to largely cancel a low frequency pole (p1) of the feedback loop of the first amplifier (20).

    摘要: Reducing, at a common sense electrode of a group of sensors of a system, a common charge flow due to a common motion of the group of sensors is presented herein. The group of electromechanical sensors generates a common charge flow as a result of a common motion of the group of electromechanical sensors and a differential charge flow as a result of a differential motion of the group of electromechanical sensors - respective sense elements of the group of electromechanical sensors being electrically connected at the common sense electrode. The system further comprises a voltage-to-voltage converter component that generates, via an output of the voltage-to-voltage converter component, a positive feedback voltage, and minimizes the common charge flow by coupling, via a defined feedback capacitance, the positive feedback voltage to the common sense electrode - the common sense electrode being electrically coupled to an input of the voltage-to-voltage converter component.
