摘　　要：　文章提出了一种基于数字锁相技术的BPSK数字解调电路的设计方案,详细描述了典型模块的设计思路。该电路可应用于符合ISO/IEC14443B类的非接触IC卡系统基站,采用0.8μmCMOS工艺实现,设计工作频率为13.56MHz,数据流率为106kbps。文中给出了利用CadenceLDV前后仿真以及Hspice模拟的波形,以及CPLD验证和实际流片后的测试结果。A BPSK demodulation IC based on DPLL is presented. The circuit can be used in contactless IC card base station, which is in compliance with ISO/IEC 14443 Type . The architecture of typical modules is described in detail. The design has been implemented in 0.8 μm CMOS technology. The operating frequency of the circuit is 13.56 MHz and its data flow-rate is 106 kbps. Results from Cadence LDV and Hspice simulations are discussed, and finally, test results of CPLD verification and the actual chip are given.
