Abstract
A stylus includes a first sensor configured to receive a first receive signal from a touch sensor of a device, and a second sensor configured to receive a second receive signal from the touch sensor of the device. The stylus includes an amplifier coupled to the first and second sensors and configured to produce a third signal by amplifying the difference between the first receive signal and the second receive signal. The stylus includes a controller configured to decode information encoded in the first receive signal and the second receive signal by processing the third signal.
