【Abstract】 The most significant features of contactless integrated circuit (IC) card system are the combining of the radio frequency identification technology and the IC card technology, and it solves the problems of non-energy and non-contact. The contactless IC card has many advantages, such as high reliability, security, high processing speed, large storage capability and ability to process several IC cards at the same time and so on. Therefore, the study and design of the contactless IC card have important applications in the informational technology.Based on the deep study of relate theories and technologies, this thesis has finished the analysis, design and simulation of the contactless IC card’s RF interface circuits and the EEPROM system. According to the ISO/IEC 14443 standard, the difference between Type A and Type B cards and the demodulation circuits of these two kinds of cards are analysed and simulated. To satisfy the demands of the data security, confidentiality and so on, several arithmetic schemes for data security are discussed. The RF interface circuit, charge pump circuit and timer circuit are mainly analysed and designed. In accordance with the requirement of a very high voltage, the charge pump circuit has been analysed and discussed particularly. Timer for EEPROM system also has been desighed and simulated. Finally, the layout of the RF interface circuit is designed.更多还原
