Abstract

The invention relates to a DEPFET transistor (1) for detecting a radio-generated signal charge (2) and for generating an electronic output signal in a manner dependent on the detected signal charge (2) according to a predetermined characteristic curve. The invention provides for the characteristic curve to have a degressive characteristic curve profile in order to combine a high measurement sensitivity in the case of small signal charges (2) with a large measurement range through to large signal charges (2).
