Status of Analytical Optimization of FET LNAs Using Noise Transformation Matrix (Invited Paper)

Noise optimization for FET low noise amplifiers (LNAs) are demonstrated through insights gained from analytical formulations derived using noise transformation matrix. The invited paper reviews the status of analytical noise optimization of FET LNAs including single-/dual-band FET LNAs with the lossless/lossy input match networks and broadband FET LNAs with the lossless input networks.
