摘要

本文提出了一种用于无线传感器网络的1.9GHz低功率发射机。它使用薄膜体声谐振器(FBAR)产生射频载波，并与天线共同设计。当从650mV电源辐射1.2mW时，双通道发射器的效率为46%。具有50%的开关键，功耗1.35mW，支持高达330kbps的数据速率。1.2times0.8mm2的发射器采用0.13 mm的CMOS，并集成到38times25times8.5mm3的太阳能传感器节点中

A 46% Efficient 0.8dBm Transmitter for Wireless Sensor Networks

This paper presents a 1.9GHz low power transmitter for wireless sensor networks. It uses film bulk acoustic resonators (FBAR) for RF carrier generation and is co-designed with the antenna. The two-channel transmitter is 46% efficient when radiating 1.2mW from a 650mV supply. With 50% on-off keying, it consumes 1.35mW and supports data rate up till 330kbps. The 1.2times0.8mm2 transmitter is implemented in 0.13mum CMOS and is integrated into a 38times25times8.5mm3 solar powered sensor node
