英文摘要：

In order to meet the requirement of flexible work mode configuration and frequen- cy calibration for RFID transceiver, the design of programmable configuration module based on new double buffer storage structure and adaptive frequency calibration（AFC） scheme is present- ed. By applying the double buffer architecture and data synchronization method, the design was simplified. A variable step factor was adopted in auto-adaptive frequency calibration scheme to shorten the time of frequency lock mode. The chip was fabricated using TSMC 0. 18μm CMOS technology with the chip area 4 mm2 and supply voltage 1.8 V. The test results show that the module can work correctly and the AFC frequency lock time was shortened less than 135 Vs.
