In this paper, we present a systematic synthesis methodology for fully integrated wideband low noise amplifiers that simultaneously optimizes impedance matching, noise figure, and other performance parameters. Leveraging an accurate analytical model, we hierarchically couple global optimization techniques with local convex optimization methods to efficiently locate optimal wideband LNA circuits. The results indicate that the methodology yields significant improvement in key LNA design constraints over existing methodologies while achieving up to one order of magnitude speedup in computational performance.
