A receiving device and a method for operating a receiving device are provided in which a signal is divided into two separate signal parts. The two signal parts are demodulated simultaneously and, from the demodulated signals, the difference is formed. After the formation of the difference, an information item is obtained from the difference signal and compared with a predetermined information item. In the case of correspondence of the obtained information and the compared information, a wake-up signal is generated.

Wake-up circuit in receiving device and method of operating the receiving device

An electronic appliance comprising an electrical circuit and an operating mode switching unit which can be awakened out of a sleep state into a working state in which the current consumption of the circuit is greater in than in the sleep state. To receive a radio signal, the appliance has a receiver comprising a UHF carrier that is amplitude-modulated by a modulation signal. The receiver comprises a UHF antenna connected to a passive filter stage to an input of a passive rectifier circuit. An output of the rectifier circuit is connected to a detector for the modulation signal. To wake the electrical circuit from the sleep state, the operating mode switching unit has a control connection to the detector. The appliance has a low current draw in the sleep state by matching the output impedance of the rectifier circuit to the input impedance of the detector.
