<p>An array of Corbino disks (10, 12, 14, 16) are connected in series to provide a high sensitivity magnetoresistor device with a total resistance determined by the number of disks in the array and their geometries. Each Corbino disk has a hub terminal (10a, 12a, 14a, 16a) on a layer of magnetoresistor material (18, 20), and a surrounding conductive shorting ring (10b, 12b, 14b, 16b). The disks are connected in an alternating series connection with alternate interdisk connections made between the hub terminals of successive disks, and the intermediate inter-disk connections made between the shorting rings of successive disks. Current flow through the array thus alternates between hub terminal-to-shorting ring and shorting ring-to-hub terminal for successive disks. The disks are preferably provided in pairs on mutually isolated islands, with the shorting rings and hub terminals on opposite surfaces of the disks. The shorting rings for each disk pair intersect generally tangentially to electrically connect the disks, while connections between successive disks on successive islands are made by leads (22a, 22b, 22c) running along the substrate between the hub terminals for those disks. The Corbino disk magnetoresistive array may be used in applications requiring high accuracy and having high operating temperatures, such as automobiles.</p> |
