Abstract： Smart hand band electrocardiogram monitoring has become a core device for civilian cardiovascular health screening due to its advantages of portability, low power consumption and constant monitoring. However, limited by wearable collection scenarios and micro-integrated circuit architectures, the monitored signals suffer from errors such as baseline drift, motion artifacts, amplitude distortion and noise interference, which cannot meet the accuracy requirements of quasi-medical level monitoring. Focusing on the hardware-level error sources of integrated circuits for hand band ECG monitoring, this paper systematically analyzes the error generation mechanisms of analog front ends, analog-to-digital conversion, power management and signal processing chips. Combined with the design constraints of low power consumption and miniaturization of wearable devices, a comprehensive optimization scheme based on high common-mode rejection amplification circuit, adaptive filter integrated circuit, highprecision analog-to-digital conversion (ADC) architecture and on-chip real-time calibration is proposed.
