研究目的
To present a PPG sensor integrating an array of dedicated pinned-photodiodes (PPD) with a full readout chain integrated in a 0.18 μm CMOS Image Sensor (CIS) process for continuous health monitoring.
研究成果
The proposed PPG sensor demonstrates a significant reduction in power consumption while maintaining high sensitivity and low noise performance, making it suitable for continuous health monitoring applications.
研究不足
The technical and application constraints of the experiments include the limitation by the few mA of the LEDs driving current and the potential for further optimization in power consumption and noise reduction.
