Abstract
Provided is touch signal detection apparatus configured to calibrate an error of a touch signal, the touch signal detection apparatus including a first digital-to-analog converter (DAC) configured to provide a first calibration voltage, a second DAC configured to provide a second calibration voltage, an attenuator configured to attenuate the second calibration voltage and provide the attenuated calibration voltage, an adder configured to add the first calibration voltage and the attenuated calibration voltage, a calibration amplifier configured to amplify a difference between a touch signal generated by detecting touch input and output of the adder with gain greater than 1 and output the difference, a sample-hold unit configured to sample and hold output of the calibration amplifier, and an analog-to-digital converter (ADC) configured to convert output of the sample-hold unit into a digital code.
