摘要

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.
