Abstract :
A description is presented of a single-chip, microcomputer-based pacemaker system in which high-level analog functions are integrated on the same IC as a 8-bit microcomputer and a DC-DC converter. Low voltage and low current techniques are used, as well as circuitry to compensate for any long-term drift of transistor characteristics. Each functional block is programmable and can therefore be used in a variety of other implantable, biomedical applications
