DATENTRÄGER MIT EINER AKTIVEN SIGNALVERARBEITUNGSSCHALTUNG UND EINER PASSIVEN SIGNALVERARBEITUNGSSCHALTUNG |
摘要 |
In a data carrier ( 1 ) and in an integrated circuit ( 5 ), a first signal processing circuit ( 8 ) with a signal-independent power supply is provided for processing a signal stream (SF 1 ) in accordance with a first transmission protocol, and a second signal processing circuit ( 9 ) with a signal-dependent power supply is provided for processing a signal stream (SF 2 ) in accordance with a second transmission protocol, which signal stream (SF 2 ) in accordance with the second transmission protocol comprises a signal characteristic, namely a lead signal (VLS), and a detection circuit ( 25 ) is provided, which detection circuit is designed for detecting the lead signal (VLS) and ensuring the supplying of the second signal processing circuit ( 9 ) with power from a power source ( 14 ) provided for the second signal processing circuit ( 9 ) following a recognition of the occurrence of the lead signal (VLS). |
