本文提出了一款45nm CMOS工艺的近场通信（NFC）无线电收发器，在卡模拟模式下实现了0.15A/m的接收灵敏度和4mA的电流消耗。该设计支持0.15至12A/m的宽动态场强范围，满足多个NFC标准的要求。

Compliance to multiple NFC standards [1-3] requires designs to support wide dynamic range of field (0.15 to 12A/m), multiple data rates (1.65 to 848Kb/s), various modulation transition times (0.01 to 8usec), wide range of modulation indices (8 to 100%) and line coding techniques (Manchester, NRZ, Modified Miller and PPM). Also, support for small antenna size and very low power card emulation (tag) operation results in additional design constraints. The solution described here integrates all the NFC
