Abstract
An example electronic device includes an active digital pen sensor surface to generate analog position information, wherein the active digital pen sensor surface includes a projective capacitive sensor layer with a variance of sheet resistance of less than plus or minus 20 percent. The electronic device also includes a controller, including a sigma-delta analog-to-digital (A-to-D) converter, to generate digital pen position information based on the analog position information, and perform a triangulation based on the digital pen position information to determine a pen position.
