Abstract
The present disclosure discloses a touch sensing signal processing circuit which senses a change in capacitance of a sensing node for touch sensing and provides a logic signal corresponding to the touch sensing. The touch sensing signal processing circuit of the present disclosure is configured using a delta-sigma analog to digital converter. Auto-tuning may be performed by delta-sigma analog conversion.
