本文提出了一种用于双电极生物电位记录的低功耗放大器，功耗仅4.6µW，噪声效率因子为3.3。该放大器能够承受高达133VPP的共模干扰并实现102dB的总共模抑制，解决了传统双电极记录中因大共模干扰导致的饱和或共模转差模问题。
crucial in delivering vital information for medical diagnostics and research applications. Recently, the demand for biopotential recording using two electrodes has grown thanks to its better user experience and lower cost than counterparts with three electrodes [1,2]. However, a two-electrode recording IC suffers from a large common-mode interference (CMI) over 100VPP [3], potentially saturating an analog front-end (AFE) or resulting in large CM to differential-mode (DM) conversion. These challenges necessitate biopotential AFEs to possess a large CMI tolerance as well as a high total common-mode rejection ratio (T-CMRR) while providing excellent noise efficiency with low power consumption. Figure 15.7.1(a) depicts a simplified electrical
