Abstract

In this paper, we present a SoC design of remote terminals for wireless telemetry system based on DS-CDMA technology. Wireless telemetry systems are data collecting system that gather the information data, such as temperature, pressure, humidity and etc, from lots of remote measurement points using wireless communication to the central unit. It can be used in ISM band having the severe interference because of the DS-CDMA technology and more than 1,000 remote terminals within 300m can be serviced at the same time. We designed the remote terminals as a SoC that is consisted of modem, digital IF, and analog circuit using a 0.25/spl mu/m single-poly five-metal CMOS process. The SoC implementation is essential for low cost and low power to satisfy the requirements of the wireless telemetry systems that need large amounts of remote terminals.

无线遥测系统远程终端的SoC设计

本文提出了一种基于DS-CDMA技术的无线遥测系统远程终端的SoC设计。无线遥测系统是将多个远程测量点的温度、压力、湿度等信息数据通过无线通信传输到中心设备的数据采集系统。由于采用了DS-CDMA技术，所以可以在干扰比较严重的ISM频段使用，可以同时服务300米以内的1000多个远程终端。我们采用0.25/spl mu/m的单聚五金属CMOS工艺，将远程终端设计成由调制解调器、数字中频和模拟电路组成的SoC。为了满足需要大量远程终端的无线遥测系统的要求，SoC的实现对于低成本和低功耗至关重要。
