pp: 1321-1325A New Computer Aided LNA Design Approach Targeting Constant Noise-Figure and Maximum GainNiladri Roy and Vijay K. Devabhaktuni doi:10.2529/PIERS070416143017 Downloads: 2026 Abstract:Low-noise amplifiers (LNAs) are critical to a wide variety of electronic circuits such as those used in aerospace and Bluetooth applications. Because of the way noise propagates through a system, LNAs are desired to have a low noise-figure and a high gain. In this paper, we propose an RF/microwave-oriented LNA design approach based on constrained line search optimization, which targets a maximum gain for a specified noise-figure. The proposed approach is automated and hence requires minimal user-intervention. Simulation results show that the approach is extremely effective in terms of meeting the user-defined specifications.References:1.
