"Low Power Analog CMOS for Cardiac Pacemakers" is a technical book that presents innovative techniques for reducing power consumption in analog integrated circuits. The focus is on the pacemaker sense channel, which serves as an example for a broader class of biomedical circuits aimed at qualitatively capturing biological signals. The first two chapters provide a comprehensive introduction to implantable medical devices and pacemakers from the perspective of circuit designers. The topic is explored in depth through requirements and solutions applied in the implementation of an industrial IC for pacemakers. The book addresses power consumption reduction on three levels: the base technology, performance-oriented analytical synthesis methods, and circuit architecture. It is aimed at professionals and students involved in the development and optimization of medical devices.
