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……
