Abstract
The invention relates to a device () for controlling a sensor (), comprising a converter unit () for converting an input signal () into a control signal () for controlling said sensor (), and a comparison unit () for determining a differential signal () that indicates the difference between said input signal () and control signal (). The device also comprises a feedback unit () for regulating the input signal () using said differential signal (). A differential signal () transfer function has a zero point at a sensor () operating frequency which does not equal zero.
