摘要

提出了一种基于0.18 um CMOS技术的数字基带收发器。基带物理层支持多速率2FSK全数字化调制解调。该解调器在14dB信噪比和100Kbps下达到10-4误码率。当PER为10-2时，2FSK接收机灵敏度达到-94dbm。采用0.18 um CMOS工艺，解调器占用0.19mm2的有源面积。MAC层兼容IEEE 802.15.4协议。协议层由单片机处理。数字基带是SOC的一部分，具有多通道、多模式的特点。它的工作频率是400mhz或2.4 GHz。该芯片主要应用于RFID、WBAN等短距离无线通信系统。

A 0.18 Um CMOS reconfigurable digital baseband transceiver with 2FSK for RFID

This paper presents a digital baseband transceiver in 0.18 um CMOS technology. The PHY layer of the baseband supports multi-rate 2FSK modulation and demodulation with fully digital way. The proposed demodulator reaches 10-4 BER for 14dB SNR and 100Kbps. The 2FSK receiver sensitivity reaches -94dbm when PER is 10-2. Using 0.18 um CMOS process, the demodulator occupies an active area of 0.19mm2. The MAC layer is compatible with IEEE 802.15.4 protocol. The Protocol layer is processed by the MCU. The digital baseband is a part of SOC, which is multi-channel and multi-mode. And it works at 400 MHz or 2.4 GHz. This chip is mainly applied to short-range wireless communication system such as RFID or WBAN.
