PHOTOPLETHYSMOGRAM (PPG) SENSING MODULE AND DEVICE INCLUDING THE SAME

Provided is a photoplethysmogram (PPG) sensing module including one or more light sources that emit light to a user; a plurality of optical sensors that receive reflected light from the user and generate sensing signals, each of the sensing signals being generated by one of the optical sensors; a read-out signal generating circuit that receives the sensing signals from the optical sensors and generate read-out signals by performing an analog-to-digital conversion on the sensing signals; and a signal processing circuit that receives the read-out signals, classifies the read-out signals according to one or more movement patterns of the user, measures a movement component of the user based on the classified read-out signals, and generates a PPG signal in which the movement component is removed.
