The ion-sensitive field-effect transistor (ISFET) has emerged as a critical component in modern sensor technology, offering rapid and robust methods for detecting ion concentration in various media.

A recently published Design Idea shows a biasing circuit for the ISFET (Reference 1). The circuit in Figure 1 provides a simpler and more accurate implementation. Voltage V A sets I D , the drain ...

The Fraunhofer-Institute for Photonic Microsystems IPMS has achieved another milestone in chemical liquid analysis. The electronics required to control the ion-sensitive field effect transistors ...

At the recent 2018 IEEE International Electron Devices Meeting (IEDM), TSMC and National Tsing Hua University presented a paper on an ion detector or pH sensor based on a 16nm finFET technology.
