Abstract
Methods are described for the design and fabrication of the sensor circuits on the polarographic oxygen sensing electrodes. The discussion includes: a method for the +5V single-supply driving for the sensor circuits, a method of low power comsumption for the front-end electronics. Typical polarograms for the commercial DO probes using this sensor circuits are presented. High accuracy of the I to V conversion using the circuits is verified.
