Signal Chain Basics #85: What’s the Difference Between Gain Bandwidth Product & Unity Gain Bandwidth?

A common problem that engineers are faced with is the need to determine the closed-loop bandwidth of their operational amplifier (op amp) circuit. Some data sheets specify unity-gain bandwidth while ...

Reduce Amplifier Noise Peaking To Improve SNR

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 ...
