| Abstract(in English) | Noncontact electrodes are a promising alternative to achieve a more comfortable and long-term biosignal recording. However, the contact capacitance of them are very sensitive, such that the imbalance between the capacitance of the noncontact electrodes could severely reduce the common mode rejection ratio (CMRR) of the biosignal amplifier, which makes the common-mode (CM) noise a more significant interference than circuits with other kinds of electrodes. In this work, we proposed a novel method to solving this problem, which was implemented by two different kinds of circuit designs. We explained the principle by calculations and evaluated our designs through circuit simulations. |
