Abstract

See full text

There is provided a capacitive touch sensing system including a touch panel, a plurality of amplification units, an analog signal processing unit and an AD converter. The touch panel includes a plurality of driving electrodes intersecting with a plurality of sensing electrodes. Each of the amplification units is coupled to one of the sensing electrodes so as to output an amplified sensing signal. The analog signal processing unit demodulates a differential signal of the amplified sensing signals outputted by two adjacent amplification units or demodulates the amplified sensing signal outputted by the amplification units to generate a dc signal. The AD converter converts the dc signal to a digital signal.
