Abstract
A capacitive sensing device including a touch panel and a controller chip is provided. The touch panel includes a plurality of first electrodes and a plurality of second electrodes. The controller chip includes a plurality of input capacitors and a plurality of output resistors. The input capacitors are selectively coupled to signal inputs of the first electrodes and the second electrodes, respectively. The output resistors are respectively coupled to signal outputs of the first electrodes and the second electrodes. The input capacitors and the output resistors are configured to form bridge circuits to suppress the influence of mutual capacitance between the first electrodes and the second electrodes.
