Patent ID: 8723515

Claim:
A vertical Hall sensor circuit comprising: an arrangement comprising a vertical Hall effect region of a first doping type, formed within a semiconductor substrate and having a stress dependency with respect to a Hall effect-related electrical characteristic; a stress compensation circuit which comprises at least one of: a lateral resistor arrangement with a first resistive element and a second resistive element, parallel to a surface of the semiconductor substrate and orthogonal to each other, wherein the lateral resistor arrangement is configured to generate a stress-dependent lateral resistor arrangement signal based on a reference signal provided to the stress compensation circuit; and a vertical resistor arrangement with a third resistive element and a fourth resistive element of the first doping type configured to vertically conduct an electric current flow, and generate a stress-dependent vertical resistor arrangement signal based on the reference signal, the third resistive element and the fourth resistive element both having elongate cross-sections parallel to the main surface of the semiconductor substrate and orthogonal to each other with respect to their respective longitudinal axes of the elongate cross-sections; a first circuit configured to provide a first signal to the arrangement, wherein the first signal is based on at least one of the stress-dependent lateral resistor arrangement signal and the stress-dependent vertical resistor arrangement signal.
