Electrocardiography has a wide range of applications in monitoring heart health and diagnosing diseases, among which how to efficiently and accurately reduce noise of electrocardiogram (ECG) signals is of great significance. This paper first writes the processing flow of ECG signals and the theoretical basis of low-noise CMOS amplifiers, then analyzes the difficulties of noise optimization of CMOS amplifiers in ECG scenarios, and then proposes feasible solutions for each difficulty. Considering these influencing factors comprehensively and using a variety of noise reduction methods in a reasonable combination will actively help the noise optimization of the ECG signal. Linking the CMOS amplifier with the noise reduction processing of the entire ECG circuit can reduce the interference of noise and improve the quality of the signal, so that the ECG signal can more accurately reflect the electrical activity of the heart. This is of great significance for the monitoring and research of heart health.
