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. |

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. |
