Abstract

In recent years, the increasing emphasis on personal health monitoring has accelerated the development of wearable medical devices, with notable trends toward miniaturization, user-friendliness, and intelligent features. As a vital bioelectrical signal indicative of cardiovascular diseases and other medical diseases, the research of electrocardiogram (ECG) monitoring has become a critical focus. Typically characterized by low amplitude (0.1–5 mV) and narrow frequency bandwidth (0.05–100 Hz), ECG signals are inherently vulnerable to semiconductor circuit noise, particularly low-frequency flicker noise. This susceptibility underscores the importance of high-performance, low-noise analog front-end (AFE) circuits in ensuring accurate ECG signal acquisition. This paper first introduces classical AFE circuit designs briefly, including their internal components and functional characteristics. Subsequently, the paper systematically categorizes and analyzes various low-noise optimized designs for AFE implementations, with particular emphasis on flicker noise reduction strategies. Through structured exploration, it demonstrates both the technical feasibility and crucial relevance of advanced low-noise AFE designs, reinforcing their significant role in advancing ECG system performance.
