摘要

在本文中,我们提出了一个正在为智能尘埃项目设计的微型系统,用于测试通信链路和模拟基本功能。该系统包括一个光接收器来处理输入的激光信号,数字电路来生成伪随机数序列,一个角立方反射器(CCR)来被动地将数据传输到基站,以及一个电荷泵来产生CCR所需的电压。该电路采用0.25 /spl μ m双孔5金属层CMOS工艺制造,CCR采用MCNC MUMPS 3结构多晶硅层(MEMS)工艺制造。这些组件将安装在1.4 V锌空气助听器式电池上,整个系统可以安装在5.8 mm/spl倍/5.8 mm/spl倍/2.4 mm的封装中。

Preliminary circuits for Smart Dust
In this paper we present a miniature system that is being designed for the Smart Dust project to test the communication link and simulate basic functionality. The system includes an optical receiver to process the incoming laser signal, digital circuits to generate a pseudorandom number sequence, a corner cube reflector (CCR) to passively transmit data to the base station, and a charge pump to generate the voltages required for the CCR. The circuits are being fabricated in a 0.25 /spl mu/m twin-well 5 metal layer CMOS process and the CCR has been fabricated in the MCNC MUMPS 3 structural polysilicon layer (MEMS) process. The components are to be mounted onto a 1.4 V zinc-air hearing aid style battery and the entire system can fit into a 5.8 mm/spl times/5.8 mm/spl times/2.4 mm package.
