Photoplethysmography (PPG) Sensor Circuit Design Techniques
2022 IEEE Custom Integrated Circuits Conference (CICC)(2022)
摘要
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.
