By modifying the on-The-shelf single-ended to differential amplifier, the common-mode rejection ratio and distortion under electrodes offset scenario can be characterized. The other essential parameters such as input impedance and power supply rejection ratio can also be determined.EngineeringConference PaperSCOPUS10.1109/ICMTS55420.2023.100941302-s2.0-85153567654
