发明名称 Circuit arrangement for wirelessly exchanging data and RFID chip card device
摘要 A circuit arrangement for wirelessly exchanging data with a reader device, including an antenna for converting electromagnetic radiation into an antenna voltage, an analogue circuit for demodulating an information signal based on the antenna voltage, and a digital circuit for processing of the information signal and for receiving power from the analogue circuit. The circuit arrangement also includes a decoupling circuit, which is interconnected between the analogue circuit and the digital circuit and provides a decoupling of both circuits.
