I have addressed this topic before, but we’ll take a little deeper look at it this time. First off, we are not going to discuss the loop gain situation of Figure 1, even though trying to cope with a ...

The almost universal choice in semiconductor power amplifiers is for a unity gain output stage, and specifically a voltage follower. Output stages with gain are not unknown, 1 but they are not common.

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 ...
