— A design and optimization of 3 GHz single ended Radio Frequency (RF) Low Noise Amplifier(LNA) for wireless applications using standard UMC 0.18μm CMOS technology is reported. Designing of RF circuit components is a challenging job, since even after performing lengthy calculations and finding parameter values it is less guarantee that the design performs as expected. In view of this the optimization tool; Elitist Non-Dominated Sorting Genetic Algorithm (NSGA-II); has been employed to get the optimized starting values of components in the design. The obtained NSGA-II parameters were simulated using Cadence Spectre- RF simulator. The designed Low Noise Amplifier achieves a power gain of 14.49 dB and a minimum Noise Figure of 1.897 dB is achieved. It dissipates 11.7 mW of power out of 1.8 V supply.
