Abstract
A touch sensor includes a touch panel including driving lines, sensing lines, node capacitors between neighboring or overlapping driving lines and sensing lines, and a sensing unit electrically connected to the sensing lines and configured to sense a capacitance from the touch panel. The sensing unit includes an input resistor having a first terminal connected to at least one of the sensing lines, a first amplifier including (i) input terminals respectively connected to a second terminal of the input resistor and a first power supply and (ii) a first output terminal, a feedback resistor having a first terminal connected to the first input terminal of the first amplifier, and a feedback amplifier having an input terminal connected to the first output terminal of the first amplifier and an output terminal connected to a second terminal of the feedback resistor. The gain of the feedback amplifier is less than 1.
