Since the scalability of technology has gotten smaller, highly integrable, and more accessible, complementary metal-oxide-semiconductor (CMOS) technology has gained popularity in wireless applications. Wireless technology has become widely used in recent years, not just for consumer gadgets but also for medical sensors like body temperature and heart rate monitors. This new trend of fast information monitoring employing portable and wireless devices has adopted low noise amplifier for low energy technology. The objectives followed in the proposed research article are, analysis of recent trends on LNA requirements and designs study through literature survey and finalizing LNA topology and specifications from the chosen band (spectrum) of application.
