    摘要: A Hall-effect magnetic sensor comprises a p-type Hall element and an n-type epitaxial Hall element. The p-type element can be implanted directly on top of the n-type element. The merged Hall elements can be biased in parallel to provide a nearly zero-bias depletion layer throughout for isolation. Electrical contacts to the n-type element can be diffused down through the p-type element and positioned to partially obstruct current flow in the p-type element. Electrical contacts can be diffused into the p-type element. Each bias contact of the p-type element can be connected to respective bias contacts of the n-type element in a parallel fashion. Then, an output signal can be taken at the sense contacts of the n-type element in order to provide improved magnetic responsivity. Further provided is a method for manufacturing the Hall-effect magnetic sensor.

    摘要: An integrated circuit magnetoresistive speed and direction sensor generally utilizes an AMR bridge circuit thereby allowing for increased air gap performance as compared to conventional Hall-effect element based sensors. The AMR sensor is capable of sensing ring magnets or bar magnets magnetized with one or more magnet poles along the desired travel. The number of poles of the magnet should be optimized based upon the application design. In order to obtain speed and direction information, two bridge circuits can be placed within proximity (I.e., the exact location and shape of the bridge can be determined based upon the target and desired performance) of each other. The signals of the two bridge circuits can be compared on integrated electronics. The bridges are generally rotated 45 degrees to reduce and/or eliminate offsets, which provide the sensor with a large air gap performance.
