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 ...

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 ...

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 ...

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 ...
