Current-mode CMOS stimulation systems have offered unprecedented opportunities for accurate and high through put in-vitro and in-vivo physiological studies. As these circuits are in long term contact with living organisms, they must be flexible, safe and power efficient. Any mismatch in biphasic current pulses will result in charge imbalance, leading to tissue/cell damage. Therefore, it is the most important to maintain the balance of the charge injected and retracted by the anode and the… CONTINUE READING
