Abstract:
A multi-touch sensing includes a voltage-current converter converting an input voltage into a current. A touch sensing block senses touch of an object. An amplifier includes a first input terminal connected to an output terminal of the voltage-current converter and to a first terminal of the touch sensing block. A second input terminal of the amplifier is grounded. An output terminal of the amplifier is connected to a second terminal of the touch sensing block.
