Abstract
A sensor arrangement to sense an external signal comprises a sensor () and a charge generator () to generate a compensation current (Ic) to compensate the sensor current. A charge generator () comprises a first transistor () having a parasitic capacitor () and a first conductive path. The charge generator () comprises a second transistor () having a second conductive path being coupled in series to the first transistor () and coupled to the output node (O) of the charge generator (). The control circuit () is configured to control the conductivity of the respective first and second conductive path of the first and the second transistor () of the charge generator () so that the sensor current is compensated by the compensation current (Ic).
