Abstract
A Hall plate excitation system provides reduced offset and temperature dependence. The Hall plate excitation system includes a current source, a switching network, and a controller. The current source is configured to provide an excitation current to a Hall plate. The switching network is configured to switchably connect the current source to each of a plurality of terminals of the Hall plate. The controller is configured to adjust the excitation current no more than once during each spinning cycle; and to sequentially switch the excitation current to each of the plurality of terminals of the Hall plate during each spinning cycle.
