Abstract
A sensing device is provided. The sensing device successively operates in a plurality of operation periods and includes a plurality of first electrodes, a plurality of differential amplifiers, and a plurality of sensing circuits. The first electrodes are disposed successively. The differential amplifiers at least comprise a first differential amplifier and a second differential amplifier. Each of the differential amplifiers comprises a first input terminal and a second input terminal. Each of the sensing circuits has an input terminal and an output terminal. The sensing circuits at least comprise first, second, and third sensing circuits. The input terminals of the sensing circuits are coupled to the first electrodes. The output terminals of sensing circuits are coupled to the differential amplifiers. The output terminal of at least one of the sensing circuits is coupled to both of the first differential amplifier and the second differential amplifier.
