When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper sibling for example, but still ...

Researchers in Sweden have demonstrated an optical amplifier which can amplify light with extremely low noise. The breakthrough enables a reach increase for optical fiber signals from e.g. 1000 km to ...

A common complaint about chopper-stabilized amplifiers is that chopper noise will interfere with the signal and cancel the positive feature of almost-negligible offset voltage and offset-voltage drift ...

Noise is all around us, and while acoustic noise is easy to spot using our ears, electronic noise is far harder to quantify even with the right instruments. A spectrum analyzer is the most convenient ...

THAT Corporation has announced the THAT1570, a new IC amplifier for high-performance signal processing. The 1570 is a low-noise high-performance differential preamplifier designed for a variety of ...

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 ...

Piezoceramic (PZT), or "piezo," actuators are known to be excellent position transducers in the nanometer or micrometer range. These actuators are widely used in many precision applications. PZTs, ...
