Abstract
The transistors (101, 124) of the sensor array (100) are configured as sensors. In addition, selection means (112-114, 116-118) are provided for selecting a transistor (124) whose condition is to be detected. The sensor (100) is set up in such a way that the selected transistor (124) can be operated as a source tracker, at least after successful selection.
Claims15
A sensor array having transistors that are coupled together, in which the transistors are designed as sensors,
- in which a means of selection is provided for selecting a transistor whose condition is to be detected,
- in which the sensor array is set up so that the selected transistor can be driven as a source follower, at least when selection has been made, and
- in which at least some of the transistors are MOS field effect transistors that are set up so that they can detect biological material.
A method for detecting a condition of a transistor in a sensor array that contains transistors coupled together,
- in which the transistors are used as sensors, so that the condition of a transistor depends on a signal to be detected, which is detected by the transistor,
- where at least some of the transistors are MOS field effect transistors that are set up so that they can detect biological material,
- in which a transistor is selected,
- in which the condition of the selected transistor is detected,
- where the selected transistor is driven as a source follower, at least when selection has been made.
