Abstract

An electronic circuit arrangement has a receiving component that detects an incoming physical signal, and supplies an electrical signal current in response thereto, as well as a control and analysis component which is fed by a supply voltage and is acted upon by the electrical signal current. The electronic circuit arrangement can be operated in a working state, in which a power is consumed, and in a rest state, in which no power is consumed. A quiescent current detector is connected in parallel to the receiving component and the control and analysis component. In the rest state of the circuit arrangement (when the supply voltage is switched off), the quiescent current detector detects the signal current supplied by the receiving component, and controls switching-on of the circuit arrangement into the operative state in response thereto.
