Abstract
In an embodiment of the techniques presented herein, a touch detection system includes a touch sensor array having transmit lines, receive lines, and unit cells defined at intersections of the transmit lines and the receive lines, a transmit sequencer configured to generate a transmit signal on the transmit lines, an analog-to-digital-converter module configured to measure responses of the unit cells to the transmit signal, and a calibration unit configured to determine a first phase offset for a first unit cell of the unit cells based on a first response, of the responses, of the first unit cell, determine a second phase offset for a second unit cell of the unit cells based on a second response, of the responses, of the second unit cell, and set a phase offset parameter of the touch sensor array based on the first phase offset and the second phase offset.
