In this paper, a preprocessing circuit for ISFETs (Ion-sensitive field-effecttransistors) to measure hydrogen-ion concentration in electrolyte is presented. A modifiedflip-flop is the main part of the circuit. The modification consists in replacing t...

Microfabricated semiconductor devices are becoming increasingly relevant, alsofor the detection of biological and chemical quantities. Especially, the “marriage” ofbiomolecules and silicon technology often yields successful new sensor concepts. Thefa...
