摘要：
A solid-state sensor assembly has a number of sensor components on or in a substrate. Each sensor component has an electrical signal converter coupled to a sensor element. Each sensor element produces a characteristic signal change in response to a sensor event. Each sensor has a an assembly maintaining a constant voltage applied to the signal converter, and a device to register the current flowing through the signal converter as a sensor signal. the signal converter is a field effect transistor whose gate is connected to the sensor element. The supply of electrical current is maintained at a constant value between the source-/drain connection in the field effect transistor. The electrical signal output is employed as the sensor signal. also claimed is an operating process.
