Inhalt:
This paper presents a system which combines a modern 350 nm mixed-signal CMOS technology with a MEMS technology for monitoring of the filter contamination level of suction and filtering systems. Therefore the system includes a piezoresistive pressure sensor, a controller core, a power management, a digital and analog signal processing with a variable gain up to 270 and an 8 bit autonomous offset adjust as well as an RFID interface to allow wireless transfer of energy and data.
