Measuring cell and measuring field comprising measuring cells of this type, use of a measuring and use of a measuring field |
摘要 |
A measuring cell for recording an electrical potential of an analyte situated on the measuring cell. The measuring cell has a sensor, a layer arranged above the sensor and electrically insulating the analyte from the sensor, and an amplifier circuit connected to the sensor on a substrate and having an input stage containing a field-effect transistor or a bipolar transistor, the sensor being at least indirectly connected to a control terminal of the field-effect transistor or of the bipolar transistor. An operating point of the amplifier circuit is set by means of a voltage or a current applied at the control terminal of the field-effect transistor or of the bipolar transistor of the input stage of the amplifier circuit. |
