Abstract
A touch screen controller for cancelling an offset capacitance of a capacitive touch screen panel includes a code generator configured to generate a time-invariant digital code and a time-variant digital code during an offset cancellation time. A switched-capacitor array converts the time-invariant digital code and the time-variant digital code into an amount of electric charges corresponding to the offset capacitance.
