Data acquisition system processor for petroleum pipes

A VLSI implementation of a data acquisition system processor for failure detection and location inside oil pipelines is presented. The DAQP02 prototype is capable of reading and storing information inside pipelines. With support for two analog signals and a 22 bits address bus, the DAQP02 is an efficient solution for in-line inspection tools known as Smart Pig. The main goal for this implementation is to minimize the physical dimension and power consumption of these equipments. The DAQP02 was manufactured in CMOS 0.8 /spl mu/m double poly, double metal, n-well technology. The experimental results agree with simulations.
