"Utilizing the trans-membrane flow of ions, bio-potential signals compose electromyogram (EMG), electrocardiogram (ECG), electrooculogram (EOG), and electroencephalogram (EEG) for purposes such as health monitoring, disease diagnosis, and human-machine interfaces. Due to the acquisition of low-operating-frequency and small-amplitude bio-potential signals in electrically noisy environments, analog front-end (AFE) systems are required to provide amplification and filtering as interfaces between the sensing electrodes and the terminal signal-processing and -rendering systems. To ensure comfort during signal acquisition, flexible substrate systems are preferred. Two essential characteristics of an AFE system are its gain-bandwidth product (GBWP) and its areal footprint (S). A figure-of-merit η≡GBWP⁄S can be defined for an AFE system, where a larger η corresponds to a more desirable system."
