Abstract
Low ground mass mitigation for pens includes sensing circuitry configured to transmit, during a first frame, a beacon signal on a first subset of sensing electrodes, the first subset being along a first axis of an input device, transmit, during a second frame, the beacon signal on a second subset of the sensing electrodes, the second subset being along the first axis and different from the first subset, and receive a pen signal transmitted responsive to the beacon signal. The processing circuitry is configured to detect a location of a capacitive pen using the pen signal.
