Implementation of Implantable Cardioverter Defibrillator

摘要

In this paper, we implement Implantable Cardioverter Defibrillator (ICD) system. In order to implement the ICD, we propose the baseband according to modulation method, modulation index and bandwidth time product. From simulation results, we decide GFSK modulation with modulation index 0.2 and bandwidth time product 0.5. Also the receiver sensitivity of ICD link budget decides −83.22dBm using receiver antenna gain, receiver power and noise figure. In test and verification of implemented SoC prototype, we obtain the packet error rate 1% at −83dBm.
