Abstract
A sensor array is provided including transistors that are coupled together. The transistors are designed as sensors and wherein the sensor array has switching devices for selecting a transistor and wherein the selected transistor's condition may be detected. The sensor array is set up so that the selected transistor is driven as a source follower and at least some of the transistors are MOS field effect transistors that are configured so that at least some of the transistors are capable of detecting biological material.

A sensor array having transistors that are coupled together, the transistors being designed as sensors, the sensor array having a means of selection for selecting a transistor as a selected transistor whose condition is to be detected, the sensor array being set up so that the selected transistor is driven as a source follower, at least when selection has been made, and at least some of the transistors being MOS field effect transistors that are set up so that the at least some of the transistors are capable of detecting biological material.
A method for detecting a condition of a transistor in
- a sensor array that contains transistors coupled together, the method comprising:
- using the transistors as sensors in such a manner 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 the at least some of the transistors are capable of detecting biological material;
- selecting one of the transistors as a selected transistor;
- detecting the condition of the selected transistor;
- driving selected transistors as a source follower, at least when selection has been made.
