Abstract: In a driving signal generating system, a boost circuit provides a power voltage, an amplifier provides an analog waveform driving signal, and a level shifter provides a digital waveform driving signal. A select device selects the analog waveform driving signal as a driving signal for a touch panel in an analog waveform mode, and selects the digital waveform driving signal as a driving signal for the touch panel in a digital waveform mode. The boost circuit provides the power voltage to the amplifier, and the amplifier, in the digital waveform mode, generates an output voltage as a power for at least one last stage of the level shifter.
