Current Feedback Amplifier Theory and
Applications
Application Note April 1995 AN9420.1



Introduction
Current feedback ampliers (CFA) have sacriced the DC In this analysis the parameter A, which usually includes the
precision of voltage feedback ampliers (VFA) in a trade-off amplifier and thus contains active elements, is called the direct
for increased slew rate and a bandwidth that is relatively gain. The parameter β, which normally contains only passive
independent of the closed loop gain. Although CFAs do not comp……
