    Abstract: A touch processor circuit includes a capacitance-to-voltage converter and an analog-to-digital converter. The capacitance-to-voltage converter converts an input signal transmitted from a touch sensor into a conversion signal corresponding to a capacitance of the touch sensor. The analog-to-digital converter digitizes the conversion signal transmitted from the capacitance-to-voltage converter and generates a digital value. The analog-to-digital converter includes a first converter, a second converter, and a combination logic circuit. The first converter calculates upper bits of the digital value based on the conversion signal during a first time period. The second converter calculates lower bits of the digital value based on a residue component signal transmitted from the first converter during a second time period. The combination logic circuit combines the upper bits and the lower bits and generates the digital value.

    Abstract: A D/A converter is configured to output tri-level potentials from an output terminal. A high potential terminal and the output terminal are connected through a p-type MOS transistor. An intermediate potential terminal and the output terminal are connected through p-type and n-type MOS transistors, which are connected in series and have low threshold voltages. A low potential terminal and the output terminal are connected through an n-type MOS transistor. The p-type MOS transistor and the n-type MOS transistor connected to the intermediate potential terminal have a positive voltage and a negative voltage between gate-source paths in off-states, respectively, and a substrate bias effect and hence remain in the off-state stably.
