Abstract:
An electronic circuit arrangement which is operable in a working state when a supply voltage is switched on, and in a rest state, resting without power consumption when the supply voltage is switched off, said electronic circuit arrangement comprising:a receiving component which detects an incoming physical signal, and supplies an electrical signal current in response thereto; a control and analysis component connected in series with the receiving component, which control and analysis component is fed by the supply voltage, is acted upon by the electrical signal current, and has a signal output, on which an electric analysis signal can be tapped; a quiescent-current detector connected parallel to the series connection of the receiving component and the control and analysis component, which quiescent-current detector, in the rest state of the circuit arrangement, detects signal current supplied by the receiving component and, generates a control signal that controls switching-on of the circuit arrangement into the operative state, in response thereto; wherein, the quiescent-current detector comprises a switch that is controllable by way of the signal current; the switch blocks in the operative state as well as in the rest state of the circuit arrangement as long as no signal current is present; the switch supplies the control signal when a signal current is present in the rest state of the circuit arrangement.
