Abstract
A circuit configuration for receiving an OOK-modulated signal, in particular for use in a data carrier of an identification system. The configuration has a demodulator circuit, a decoding circuit that is connected downstream of the latter and a sequential control for controlling in particular the reception, demodulation and processing of received data. A switching element that is driven by the sequential control is disposed between the demodulator circuit and the decoding circuit. An input of the switching element is connected to the output of the demodulator circuit and a first output of the switching element being connected to the input of the decoding circuit. The switching element has a second output that is connected to the reset input of the circuit configuration.
