Abstract
A receiving circuit for a communication unit of an access device has a resonance circuit () with a receiving coil (L) for converting a magnetic induction into electrical current, and a capacitor (C). The receiving circuit () further has a first resistor (R) and a switching element () designed for controllably connecting and disconnecting the first resistor (R) to the resonance circuit (). The receiving circuit electrically connects the resonance circuit () to the first resistor (R) when the circuitry of the resonance circuit () changes from a first circuitry () to a second circuitry (), and electrically disconnects the first resistor (R) from the resonance circuit () when the circuitry of the resonance circuit () changes from the second circuitry () to the first circuitry ().
