Abstract :
A new realization of a Current Feedback Amplifier (CFA) is introduced, and a description of its properties is provided. It is shown that this new realization offers several advantages in comparison with conventional CFAs and may be useful in certain design applications. Theoretical derivations are presented, stability issues are examined, and laboratory measurement results are given.
