Diode sensor matrix and method of reading out a diode sensor matrix |
摘要 |
A diode sensor matrix including a multitude of diodes is configured to detect, in a first measuring cycle, a first sensor value at a first diode or at diodes of a first group of diodes while operating the first diode and/or the diodes of the first group in the flow direction and operating the diodes, which share an anode or cathode or terminal with the first diode or with any of the diodes of the first group, in the reverse direction, and to detect, in a second measuring cycle, a second sensor value at a second diode among the diodes which share an anode or cathode terminal with the first diode or with any of the diodes of the first group, while operating the second diode in the flow direction and operating the first diode or a diode from the first group in the reverse direction. |

1. A diode sensor matrix comprising a multitude of diodes, wherein each of the diodes shares one anode terminal with at least one other diode and one cathode terminal with at least one further, different diode, the diode sensor matrix being configured to detect, in a first measuring cycle, a first sensor value at a first diode or, respectively, at diodes of a first group of diodes which share at least one anode or cathode terminal amongst themselves, respectively, specifically while operating the first diode and/or the diodes of the first group in the flow direction and while operating the diodes, which share an anode or cathode or terminal with the first diode or with any of the diodes of the first group, in the reverse direction, and to detect, in a second measuring cycle, a second sensor value at a second diode among the diodes which share an anode or cathode terminal with the first diode or with any of the diodes of the first group, specifically while operating the second diode in the flow direction and while operating the first diode or a diode from the first group, with which the second diode shares an anode or cathode terminal, in the reverse direction;
the diode sensor matrix further comprising a first plurality of control lines configured to provide a first measuring potential or a second measuring potential; a second plurality of control lines configured to provide a first blocking potential and a second blocking potential; and a controller configured to connect the respective anode or cathode terminal of a diode of the multitude of diodes to a control line of the first multitude of control lines or to a control line of the second plurality of control lines in a switchable manner. |
