Abstract: 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.

Abstract: In managing temperature in a system on chip (SOC), a main temperature signal is generated using a main sensor, where the main temperature signal is a signal having a value corresponding to a main temperature of the SOC. Subsidiary temperature signals are generated using subsidiary sensors, where the subsidiary temperature signals are pulse signals having frequencies corresponding to subsidiary temperatures of subsidiary blocks in the SOC, respectively. An operation of the SOC is controlled based upon the main temperature signal and the subsidiary temperature signals.
