摘要:
A plurality of bridge transducers are provided in a dual arrangement. An output terminal from each transducer is coupled to differential inputs of an amplifier. Each of the other outputs from the transducers are respectively coupled together and used to control a bias for dual active loads. The transducers may be implemented within monolithic silicon integrated circuits, using bipolar technology with Hall effect, magnetoresistive or piezoresistive sensing elements for the bridge. A single Hall effect transducer may be coupled to the inputs of the differential amplifier, and a center tap terminal used to control a bias for dual active loads.
