Abstract
A semiconductor body has formed on it at least two hall effect plates each having a pair of oppositely positioned current contacts and a pair of oppositely positioned hall voltage contacts, the hall effect plates being positioned with respect to each other such that a line of one bisecting the current terminals is generally orthogonal to a line of the other bisecting the current terminals. Means are provided for applying a voltage across the current terminals of both of the hall plates and means are provided for selectively applying a magnetic field that intersects substantially perpendicularly the plane of the hall plates. The positive hall voltage contacts are connected together and the negative hall voltage contacts are connected together, with output circuitry connected to this interconnecting circuitry for receiving and transmitting an electrical signal indicative of the presence of the intersecting magnetic field.
