System on a chip for petroleum pipeline inspection

The present paper describes the implementation and experimental results of the DAQP02 system on a chip (SoC) for petroleum pipeline inspection. This integrated circuit is able to read and process information about physical phenomena inside pipelines. The DAQP02 has two multiplexed analog inputs, one 8-bit A/D converter, an 8-bit data bus and a 22-bit address bus. Due to its small dimensions and low power consumption features, it is an efficient in-line inspection tool. The integrated circuit was manufactured in CMOS 0.8 /spl mu/m double poly, double metal, n-well technology.
