The invention aims to improve the accuracy of signal acquisition systems, particularly in biomedical applications, by dynamically compensating for impedance mismatches between electrodes and skin interfaces. It integrates common mode current sources, a differential amplifier, and a PID-controlled variable gain amplifier (VGA) to adjust for voltage differences caused by these mismatches. This approach enhances the reliability of medical diagnostics and other sensitive electronic measurements, ensuring precise data collection even in environments prone to electromagnetic interference.
