Design and optimization of LNAs through the scattering parameters

摘要

This brief presents a symbolic approach for the optimal design of low noise amplifiers through the scattering parameters. An optimization algorithm, which is also proposed in this paper, generates the optimal values of all the design parameters that meet imposed specifications on the scattering parameters. ADS simulations, using 0.35µm CMOS technology, are presented to show the good agreement between theoretical and simulation results.
