Abstract
A circuit for detecting electromagnetic radiation such as infrared radiation includes one or more sensor elements which convert the electromagnetic radiation into an electric signal. A field effect transistor receives the electric signal of the sensor elements. An impedance which is ohmic, inductive, or both is connected between the supply voltage and the field effect transistor to filter high frequencies so that false detections by the detecting circuit are eliminated.
