Patent ID: 7573112

Claim:
A magnetic sensor, comprising: a substrate including circuitry; at least one conductive layer to interconnect the circuitry; an insulator layer to electrically insulate the at least one conductive layer; first and second conductive layers generally parallel to the substrate; a dielectric layer disposed between the first and second conductive layers such that the first and second conductive layers and the dielectric layer form a capacitor; and first and second terminals, wherein the first terminal is coupled to a voltage supply terminal and is electrically connected to the first conductive layer, and the second terminal is coupled to a ground terminal and is electrically connected to the second conductive layer, wherein the first conductive layer is separated to further comprise a third conductive layer electrically connected to a third terminal coupled to a voltage output terminal, and the dielectric layer is further disposed between the third and second conductive layers such that the third and second conductive layers and the dielectric layer form a second decoupling capacitor.
