Abstract :
System performance and realizability of smart sensors all depend on proper analog-digital signal processing. This paper presents a sensor signal conditioning IC using standard 0.18um CMOS technology which delivers 16bit-precise measurement results for resistive bridge-type sensors via a serial digital interface. The presented IC, ZSSC3016 can operate in applications with poor power supply while consuming a minimum of current. A general motivation for sensor signal conditioning is given. The system architecture, main functional blocks and simulation and measurement results are shown and described.
