Test system incorporating a field effect transistor sensor
A test system in accordance with the invention includes a field effect transistor (FET) sensor that is operable to detect an electric field present in an area located adjacent to a sensor surface of the FET sensor and generate thereby, a change in the drain-source current of the FET sensor. The chan...

Zusammenfassung: | A test system in accordance with the invention includes a field effect transistor (FET) sensor that is operable to detect an electric field present in an area located adjacent to a sensor surface of the FET sensor and generate thereby, a change in the drain-source current of the FET sensor. The change in drain-source current is typically detected by a current detector of the test system. |
