  • Patent number: 11327045
    Abstract: A sensor device includes a substrate, first and second source regions, first and second drain regions, first and second channel regions, and first and second gate structures disposed over the first and second channel regions respectively. The source regions and drain regions are at least partially disposed within the substrate. The second gate structure includes first and second gate elements, and a resistance region configured to provide a resistance to a second current flow through the second channel region. In use, the first gate structure may receive a solution, and a change in pH in the solution changes a first current flow through the first channel region. In turn, the second current flow through the second channel region changes to compensate for the change in the first current flow to maintain a constant current flow through the sensor device.
