Abstract
Official abstract text for this publication.
An active stylus is disclosed. The stylus includes an electrode at a tip of the stylus; and powered circuitry coupled to the electrode and configured for capacitively coupling the electrode with a capacitive touch sensor panel. The powered circuitry can further include drive circuitry configured to output a drive voltage at the electrode and/or sense circuitry configured to sense a voltage received at the electrode.
First claim
Opening claim text (preview).
What is claimed is: 1. Capacitive sensor circuitry, comprising: one or more sense channels coupled to a plurality of sense lines, the one or more sense channels configured for detecting a change in capacitance between an active stylus generating a stimulation signal and the one or more sense lines to determine a location of the active stylus proximate to the one or more sense lines; wherein the one or more sense channels comprise: a sense amplifier to adjust a detected change in…
