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 ...

Bismuth-doped fibre amplifiers and lasers have emerged as promising alternatives to conventional rare-earth-doped devices, providing a broader spectral coverage that is particularly beneficial for ...

Previous installments of this article series discussed the need to verify SPICE model accuracy and how to measure the output impedance, small-signal bandwidth, and input-referred errors of operational ...

Digital predistortion is an approach to amplifier linearization that permits the efficiency of the multi-carrier amplifier to be dramatically increased. The principle of predistortion is intrinsically ...

One of the great ironies in broadcast engineering is that we all grew accustomed to generating large of amounts of linearly modulated RF with amplifiers that were themselves very non-linear whether it ...
