Original Abstract

The microelectronic measuring system for conductivity electrochemical sensor measurement of liquid materials properties was designed in CMOS technology. The main parts of the system are current source with switchable ranges, the sensor switches allowing change of the current polarity in compliance with the bipolar pulse method, which was developed specially for this measurement purposes at the Dept.of Microelectronics. The most important part of the system is a sensor voltage drop measuring circuit using opamp offset switched compensation.
