Abstract :
The Cochlear Microphonic is one of the electrical potentials generated by the ear in response to audible stimuli. It is very difficult to measure the CM non-invasively because it has a very small magnitude (less than 1 μV). A high Common Mode Rejection Ratio (CMRR) and very large bandwidth (5 Hz–20 kHz) biomedical amplifier system is presented to measure the signal. The system also uses a driven right leg circuit to increase the CMRR.
