发明名称 ISFET switch
摘要 There is provided a semiconductor device for detecting a change in ion concentration of a sample and method of using same. The device can have a plurality of Field Effect Transistors (FETs) coupled to a common floating gate and an ion sensing layer exposed to the sample and coupled to the floating gate. There may be other input voltages coupled to the floating gate.

主权项 1. A semiconductor device for detecting a change in ion concentration of a sample, the device comprising: a plurality of Field Effect Transistors (FETs) coupled to a common floating gate; and an ion sensing layer exposed to the sample and coupled to the floating gate; a circuit comprising the plurality of FETs to provide a digital output whose state depends on the ion concentration of the sample; and one or more first electrical input signals coupled to the floating gate for removing or adding a charge to the floating gate to set a switching threshold for the plurality of transistors.
