Power approaches for medical Implantable devices using Vlsi design techniques

Abstract

The health industry is advancing towards a healthier society by newlinemaking innovations in the treatment process and the diagnosis phase. The newlinemedical field research has brought medical devices that help in early diagnosis, newlinetreatment, and function to substitute specific malfunctioning organs. Wearable newlineMedical Devices (WMD) and Implantable Medical Devices (IMD) with newlinebiosensors are used for diagnostic and therapeutic purposes for various human newlineailments. These devices have made possible early diagnosis, remote monitoring, newlineand biological processes with minimal human interference. These type of devices newlinehelped many patients be monitored and treated in an environment of their newlinecomfort with least hindrance to their normal activities. The WMD and IMD have newlinedrawbacks of high-power consumption leading to battery drainage and affect the newlinehealthy tissues. Battery drainage in IMD demands surgery for the second time to newlinereplace the battery. newlineThis research mainly focuses on minimizing biosensors power newlineconsumption in the implantable devices, thereby making Implantable Medical newlineDevices durable till the human lifetime. It also concentrates on reducing the area newlineoccupied by them. The architecture needs to be carefully analyzed and designed, newlineas other parameters like noise, speed, and accuracy of the signal have also to be newlineconsidered in the medical device apart from overcoming the above-discussed newlinedrawbacks. The VLSI techniques incorporated in CMOS technology, with its newlineunique feature of low-cost device fabrication with many devices on the same newlinechip, provides a dependable solution to these limitations. The architecture, power newlineconsumption techniques, Analog to Digital converters, and their functions used newlinein existing biosensors are surveyed and studied in detail as the initial step. The newlineconcepts learnt from the study have been used in designing the architectures newlineproposed in the research. newline
