Abstract: The present application discloses a sensing device, in which obtaining a first filtered signal by a first filter element according to a sensing reference signal corresponding to a sensing signal and obtaining a second filtered signal by a second filter element according to an analog reference signal, and then a noise compensation signal is generated according to the first filtered signal and the second filtered signal. Hereby, an analog-front-end circuit will decrease a noise of the sensing signal by compensating the sensing signal after the sensing signal and the noise compensation signal are received.

Abstract: The present application discloses a capacitive sensing device and a sensing method thereof. A plurality of driving signals corresponding to a plurality of driving codes are outputted to a plurality of driving electrodes, thereby, a plurality of sensing signal are generated on a plurality of sensing electrodes corresponding to the driving electrodes, where the sensing signals are decoded to sensing data by an operation circuit. Hereby, the calculation function of the operation circuit according to the present application may be simplified.
