Abstract
An apparatus includes a sinusoidal wave generator that generates, over a first analog line, an in-phase drive signal and, over a second analog line, an opposite-phase drive signal. A comparator has inputs respectively coupled to the first analog line and the second analog line and asserts a first output in response to detecting a crossing between the in-phase drive signal and the opposite-phase drive signal. Multi-phase switching logic is coupled to an output of the comparator. The multi-phase switching logic asserts a second output in response to both detecting the first output and receiving a signal indicative of a phase switch of the sinusoidal wave generator. The second output controls timing of applying a multi-phase switching pattern to sets of switches coupled between the first analog line and the second analog line and transmission (TX) electrodes of a touch panel.
