PRELIMINARY CIRCUITS FOR SMART DUST
Abstract
In this paper we present a miniature systcm 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 gcnerate a pseudorandom number sequencc, a corner cube reflector (CCR) to passively transmit data to thc base station, and a charge pump to generate the voItagcs required for thc CCR. The circuits are being fabricated in a 0.25pm twin-well S metal layer CMOS proccss and the CCR has been fabricated in the MCNC MUMPS 3 structural polysilicon lnycr (MEMS) process. The components are to bc mounted onto a 1.4V Zinc-Air henring aid style battery and thc entire system can fit into a 5 . 8 m x S.8” x 2.4” package.
