Since the first artificial pacemaker was introduced by Albert Hyman in 1932, much has changed and will continue to change in the future. The complexity and reliability of modern pacemakers has increased significantly, mainly due to developments in integrated circuit design, providing, for instance, diagnostic analysis, adaptive rate response and programmability. Nevertheless, future trends for pacemakers indicate that much more advanced signal processing methods will be required than nowadays. Furthermore, in implantable medical devices, such as pacemakers, power consumption is a critical issue, due to the limited power density and the longevity of currently available batteries. This implies that the design of such devices has to be optimized for very low power dissipation. The purpose of this book is to describe novel signal processing methodologies and analog integrated circuit techniques for low-power biomedical systems. The methodology presented focuses on the development of ultra low-power analog integrated circuits that implement the required signal processing, taking into account the limitations imposed by an implantable device.
