Claim:
1. An electrocardiogram (ECG) sensor comprising: a motion artifact detector configured to receive a channel offset coefficient, a first channel signal of a first channel, and a second channel signal of a second channel, and detect a motion artifact component from the first channel signal of the first channel and the second channel signal of the second channel based on the channel offset coefficient, the channel offset coefficient indicating a difference between the first channel signal and the second channel signal; and an ECG filter configured to receive the motion artifact component and generate an ECG signal by performing a least mean square (LMS) filtering operation on the first channel signal to remove the motion artifact component, wherein the motion artifact detector is configured to detect the motion artifact component by subtracting from the first channel signal a signal obtained by dividing the second channel signal by the channel offset coefficient.
