Worldwide, there are about 3 million people who have pacemakers, with 10,000 new implantations of ICD’s each month. [heart.org] Due to the gravity and importance of the function that ICD’s provide, these devices must be extremely reliable and highly effective. However, because of the high tolerances of IC manufacturing, stimulation circuits for pacemakers may be slightly unmatched and over time, may have a net DC charge applied to the tissues in the heart. Extra charge pumped into body tissues is dangerous for the patient’s health; the pH of the tissue can be raised and corrosion of the stimulating electrodes may occur. This project entails the study and design of methods that allow balanced stimulation of cardiac tissue. Due to the expense of manufacturing integrated circuits, this project aims only to have representative simulations of our circuit solutions. By using dynamic current matching, we hope to cancel out the DC charge inadvertently applied to the heart in a cost effective manner.
