Abstract:
A signal-noise ratio control system which reduces noise interference includes a touch sensor, a touch controller, and a level shifter. The touch sensor is driven by a driving signal and outputs an analog signal based on a touch situation. The touch controller generates the driving signal and provides a divided voltage based on the analog signal. The level shifter adjusts a voltage level of the driving signal based on a voltage level of the divided voltage.
