Abstract
A driving signal generator includes a window function code generator, a sine wave code generator, an operation circuit and a signal converter. The window function code generator generates a first code corresponding to a window of a first sine wave. The sine wave code generator generates a second code corresponding to a second sine wave, wherein a frequency of the second sine wave is higher than a frequency of the first sine wave. The operation circuit is coupled to the window function code generator and the sine wave code generator, and performs an operation on the first code and the second code to generate an output code. The signal converter is coupled to the operation circuit and generates a touch driving voltage of a driving signal by converting the output code.
