Abstract
A pen for interacting with a touch screen of a computing device includes an alternating current coupling circuit and a sense-regulation circuit. The alternating current coupling circuit receives a sense signal from the touch screen. The alternating current coupling circuit transmits a transmit signal to the touch screen. The sense-regulation circuit receives the sense signal from the alternating current coupling circuit. The sense-regulation circuit receives a representation of transmit data. The sense-regulation circuit generates a comparison signal based on the sense signal and the representation of the transmit data. The sense-regulation circuit converts the representation of the transmit data into the transmit signal.
