Title:
Integrated multipurpose analog front-end for electrochemical ISFET sensors 
Abstract:
Ion-Sensitive-Field-Effect-Transistors (ISFETs) are an alternative to the common glass electrode for pH sensing. They promise higher integration, easier manufacturing and are interesting for biological, medical and environmental applications. However, they require a different and slightly more complex readout circuit. We propose a new circuit based on a standard mixed-signal-processor with minimal required external components. The operating point of the ISFET is set with a servo loop in software...    »
