Microelectronics In Implantable Cardiovascular Devices

Abstract

Low voltage micropower circuit techniques are of crucial im­ portance for implantable devices. All analog and digital func­ tions of a physiological pacing system are implemented in a single IC -design including a unique switched capacitor design of all signal and output stages. Based on a state machine com­ bined with a microprocessor controlled signal processing sys­ tem a Autonomic Nervous System (ANS) controlled pacemaker is described.
