Abstract: A touch-sensitive apparatus includes a touch panel comprising a touch sensitive surface and at least one a drive electrode capacitively coupled to at least one receive electrode. A sense circuit generates a response signal for the receive electrode in response to a drive signal delivered to the drive electrode. A measurement circuit applies a time-varying transfer function to the response signal. The transfer function varies proportionately and synchronously with the response signal. A calibration circuit is used to match the time-varying transfer function to the response signal.

Abstract: A pen configured for use with a touch sensor includes a pen tip that is configured to make contact with the touch sensor. The pen body includes an electrically conductive receiver portion and an electrically conductive emitter portion that is electrically insulated and electrostatically shielded from the receiver portion. The pen includes circuitry configured to receive a touch sensor drive signal applied to a drive electrode of the touch sensor through the receiver portion of the pen body. In response to the received signal, the pen circuitry generates a pen drive signal that is phase additive with the touch sensor drive signal and emits the pen drive signal through the emitter portion of the pen body.
