Low-Power Photoplethysmogram Acquisition Integrated Circuit with Robust Light Interference Compensation
To overcome light interference, including a large DC offset and ambient light variation, a robust photoplethysmogram (PPG) readout chip is fabricated using a 0.13-μm complementary metal–oxide–semiconductor (CMOS) process. Against the large DC offset, a saturation detection and current feedback circu...
