Abstract

A touch circuit including an integrator circuit and a compensation circuit is provided. The integrator circuit includes a first terminal, a second terminal and an output terminal. The first terminal of the integrator circuit is coupled to a touch sensor, and the second terminal of the integrator circuit is coupled to a first voltage. The compensation circuit includes a first terminal and a second terminal. The first terminal of the compensation circuit is coupled to the first terminal of the integrator circuit, and the second terminal of the compensation circuit is coupled to a second voltage. When the touch circuit senses a sensing current from the touch sensor, the first voltage is increased and the second voltage is decreased.
