Engineers often perceive RF-low-noise-amplifier design as a difficult task. Obtaining a low-noise figure with high stable gain can be challenging—even intimidating. However, with the recent evolution ...

This article examines key parameters that contribute to amplifier noise. It explains how amplifier design, specifically the choice of bipolar, JFET-input, or CMOS-input design, affects noise. The note ...

Many amplifiers exhibit an increase in voltage noise spectral density (NSD) as they approach the unity-gain crossover frequency. This noise peaking can cause your circuits to have 39% higher noise ...

Cryogenic low-noise amplifiers (LNAs) play a pivotal role in modern high-frequency electronic systems, where the reduction of thermal noise is critical for enhancing signal detection and fidelity.
