Abstract
A chip for sensing a physiological signal comprises: an input unit for receiving a first electrocardiogram (ECG) signal; a filter for generating a second ECG signal by filtering the first ECG signal; an amplifying unit for generating a third ECG signal by amplifying the second ECG signal; an Analog-to-Digital converting unit for converting the third ECG signal into a digital signal; an operating unit for generating a plurality of analysis data by operational analyzing the digital signal; and an output unit for outputting the plurality of analysis data. Therefore, the manufacturing cost of the chip is decreased and the chip is suitable for use in small-scale devices.
