Abstract

A detector circuit, for example for optical radiation, has a detector diode (20) and an amplifier circuit (30) integrated with the diode in the same silicon wafer for amplification of the diode signal. The diode is designed as a lateral diode. The diode and the amplifier circuit are both produced in a homogeneously weakly doped silicon wafer (1).
