Low Noise Amplifier in Smart Healthcare Applications

Abstract

The smart health care monitoring systems are playing a pivotal role in the medical health industry. The wireless healthcare monitoring system is one of the leading innovative developments in the medical system. A smart wireless health monitoring system helps to measure the user's neural signals, heart rate, body temperature and any unusual activity in the patient's body. This paper reviews and surveys the various applications of a Low Noise Amplifier (LNA) in the healthcare domain, such as ECG monitoring systems, EEG monitoring Systems, neural recording system, biosensor applications, Medical implantable systems, etc. The design specifications of LNA for different applications have also been analyzed. LNA is a key element of a front-end receiver, which combines low noise figure, nominal supply voltage, high gain bandwidth, good input, and output impedance matching, etc. Finally, a comparison of the different parameters for various applications has been done and reviewed in this paper.
