Abstract:
The present disclosure is directed to an electronic circuit having a Hall effect element and a resistor bridge, all disposed over a common semiconductor substrate. The resistor bridge includes a first set of resistive elements having a first vertical epitaxial resistor and a first lateral epitaxial resistor coupled in series, and a second set of resistive elements having a second vertical epitaxial resistor and a second lateral epitaxial resistor coupled in series. The first set of resistive elements and the second set of resistive elements can be coupled in parallel. The resistor bridge can be configured to sense a stress value of the Hall effect element.
