Abstract
The wearable healthcare market is rapidly growing as fitness and wellness monitoring can significantly improve quality of life. Optical Photoplethysmography (PPG) is a vital monitoring modality and has gained tremendous interest in recent years since it can provide many biomedical parameters with good user comfort. This paper serves as a basic tutorial and reviews recent developments in PPG monitoring, especially the design techniques on building low-power and high dynamic range (DR) readout integrated circuits (ICs). The future development trends are provided as well.
