Description

With the introduction of commercially available amplifiers using the current feedback topology byComlinear Corporation in the early 1980’s previously unattainable gain and bandwidths in a DC coupledamplifier became easily available to any design engineer. The basic achievement realized by the currentfeedback topology is to de-couple the signal gain from the loop gain part of the overall tra
