A comparative study of low noise amplifier towards futuristic advancement in wireless communication

Future wireless devices are required to ensure pervasive wireless communication and quick proliferation of the virtual reality, medical imaging, and IoT infrastructure, which incorporates new and promising technologies. To promote the growth and embrace of this era of technological advancement, effective mm-wave transceiver hardware is necessary. LNA is one of the modules that has a direct impact on the performance of a transceiver. Numerous methodologies have been proposed in LNA design due to fundamental building blocks of the receiver chain, such as differential cascode, folded cascode, transformer feedback, input balun, current reuse, and gm boosting to streamline parameters such as wafer area, gain, noise figure, linearity, and power efficiency. This review investigates CMOS LNA technologies and circuit topologies for mm-wave applications. Furthermore, numerous cutting-edge LNA design aspects are compared to help foresee future CMOS LNA design approaches. This review will provide a comparative analysis and reference for future LNA for 5G and beyond networks.
