ABSTRACT:
An X-Y digitizer system is described for embedding within a host device, such as a tablet PC, a mobile telephone, a personal digital assistant or the like. The digitizer is configurable so that it can detect and track the position of different types of position indicator. The digitizer that is described also includes novel digitizer windings and novel excitation circuitry for energizing the windings.
