Abstract :
A new systematic CAD procedure for designing multistage broadband low-noise amplifiers (LNAs) is presented based on ≪region≫ and ≪visual≫ design techniques. This procedure allows the matching/feedback/compensation network synthesis directly from amplifier stage requirements. As an example, the design of X-band two-stage 0.15 μm pHEMT MMIC LNA is demonstrated.
