Abstract
This work presents the design of a low noise amplifier (LNA) using TSMC CMOS 28-nm technology, capable of operating at an ultra-low voltage of 0.2 V with a minimum power consumption of 48 \mu \mathrm{W} . The LNA achieves a gain ranging from 11.3 dB to 29.3 dB while maintaining input and output return losses below -10 dB. At maximum gain, the LNA achieves a NF of 1.93 dB. Furthermore, an optimized performance mode offers power consumption below 100 \mu \mathrm{W} , with other performance metrics remaining competitive.
