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 ...

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 ...

Many technical documents have been written on noise analysis. Early on in my career I became obsessed with operational amplifier (op amp) noise. Subsequently, I published a series of application notes ...

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 ...
