A FULLY INTEGRATED SOC FOR LARGE SCALE WIRELESS SENSOR NETWORKS IN 0.18μm CMOS

摘要：

A fully integrated system-on-chip (SoC) intended for use in large scale wireless sensor networks is built in 0.18μm CMOS.All of building blocks including embedded microprocessor ARM7TDMI, baseband modem, radio transceiver, ADC/DAC, temperature sensor and some communication ports have been integrated into a single chip.The baseband modem adopts BPSK/QPSK DSSS modulation, which symbol rate and processing gain are optional.The radio transmitter utilizes the direct modulation scheme while the receiver is based on Low-IF architecture which Rx sensitivity can achieve -92dBm.The temperature sensor on chip can provide a resolution of 0.16℃ from-55℃ to + 130℃ with an error of less than 0.7℃.
