    Abstract: Described examples include graphene Hall sensors, magnetic sensor systems and methods for sensing a magnetic field using an adjustable gate voltage to adapt the Hall sensor magnetic field sensitivity according to a control input for environmental or process compensation and/or real-time adaptation for balancing power consumption and minimum detectable field performance. The graphene Hall sensor gate voltage can be modulated and the sensor output signal can be demodulated to combat flicker or other low frequency noise. Also, graphene Hall sensors can be provided with capacitive coupled contacts for reliable low impedance AC coupling to instrumentation amplifiers or other circuits using integral capacitance.

    Abstract: A method, e.g. of forming an electronic device, includes forming a carbon-doped metal layer over a substrate. The carbon-doped metal layer is heated and cooled such that a first graphene layer is formed on a top surface of the carbon-doped metal layer, and a second graphene layer is formed between the carbon-doped metal layer and the substrate. A portion of the first graphene layer is removed and a portion of the carbon-doped metal layer is removed, thereby forming first and second spaced-apart contact layers on the second graphene layer.
