Figures of Merit for CMOS Low-Noise Amplifiers and Estimates for Their Theoretical Limits

Leonid Belostotski et al.

Summary: This brief examines the theoretical interdependence of low-noise-amplifier (LNA) performance parameters and identifies four figures of merit (FoMs) for comparison. The analysis also estimates the limits and room for improvement of these FoMs. Comparisons of regression analysis on nearly 500 CMOS LNAs published in the past 20 years show reasonable agreement with the identified trends, despite simplifying assumptions.

A Wideband CMOS LNA Using Transformer-Based Input Matching and Pole-Tuning Technique

Hongchen Chen et al.

Summary: The proposed LNA incorporates a wideband low-noise design with a novel input matching network and transformers to reduce noise figure, achieving an NF lower than 4.5 dB over a wide operating bandwidth. Furthermore, utilizing pole-tuning technique and current-reuse technique, the design achieves wider gain bandwidth and low power consumption.
