Design and implementation of biomedical SoC for implantable cardioverter defibrillators

In this paper, a biomedical processor was developed for implantable cardioverter defibrillators (ICDs), which delivers appropriate prescriptions for atrial tachycardia and fibrillation to a pacing module of ICD. The diagnosis of heart conditions is determined based on atrial electrograms (EGMs) as sensed from within the heart. The biomedical processor is implemented into a single chip including analog circuit elements. The chip is fabricated in a 0.35 μm CMOS technology, and the chip area is 3.8 × 2.7 mm².
