Also note that rs is outside the feedback circuit. 19 3 shows this adjustment added to a noninverting circuit. We see that the circuit is series series negative feedback.
Current feedback amplifiers allow an easy resistive trim for frequency peaking that has no impact on the forward gain.
Current feedback amplifiers allow an easy resistive trim for frequency peaking that has no impact on the forward gain. This application note will answer some questions and give a jumpstart to apprehensive designers. A current feedback op amp circuit collection bruce carter high performance linear products abstract designers often misunderstand current feedback amplifiers although they have been available for many years. The cfa was invented by david nelson at comlinear corporation and first sold in 1982 as a hybrid amplifier the clc103.
