Abstract

Threatening Viruses, Chronic and mutated disease are the main source of mortality, throughout the globe. It is necessary to identify these types of diseases in prior stage to reduce the risk. Though the existing diagnosing devices are used to recognize particular issue in prior stage, it engrosses more power and area. Hence it results in need of replacement within a period of time. It is emergent to design a novel Implantable biodevice, with low power, less area, low noise integrated circuit. Analog to digital convertor is an integral part of such diagnosing medical device. In this paper, we proposed a low power 5 bit flash ADC that comprises of CMOS based pre amplifier, comparator and a priority encoder. The proposed ADC has been designed for biosensor based Implantable Medical Device (IMD) in 180 nm CMOS technology, which occupies less area and obtained bandwidth in 69KHz, achieved gain as 125 dB and power consumption in 80 nW under a single 1.2 V power supply. In addition, the post layout simulation of the proposed ADC has been performed successfully which are exceptionally pertinent for low power Implantable bio devices.
