An ECG sensor chip used in a wearable appliance includes; a switch controlled &#x2014;by a switching signal, an amplifier that amplifies a difference between first and second ECG signals, and a location indicator that generates the switching signal. The switch passes either a first ECG signal or second ECG signal in response to the switching signal.

The switch passes either a first ECG signal or second ECG signal in response to the switching signal.

An electrocardiogram (ECG) sensor includes a motion artifact detector configured to detect a motion artifact component from a first channel signal of a first channel and a second channel signal of a second channel using a channel offset coefficient. The channel offset coefficient indicates a difference between the first channel signal and the second channel signal. The ECG sensor includes an ECG filter configured to generate an ECG signal by performing a least mean square (LMS) filtering operation on the first channel signal to remove the motion artifact component.
