ELECTRONIC CIRCUIT FOR DRIVING A HALL EFFECT ELEMENT WITH A CURRENT COMPENSATED FOR SUBSTRATE STRESS |
摘要 |
An electronic circuit can be disposed upon a semiconductor substrate. An epitaxial layer can be disposed over the semiconductor substrate. The electronic circuit can include a Hall effect element, at least a portion of the Hall effect element disposed in the epitaxial layer. The electronic circuit can further include a current generator configured to generate a drive current that passes through the Hall effect element. The current generator can include a resistor disposed in the epitaxial layer and having characteristics such that a resistance of the resistor can vary with a stress of the semiconductor substrate, resulting in changes of the drive current, to compensate for variations in the sensitivity of the Hall effect element with the stress of the substrate. |
