Current-feedback amplifiers versus voltage operational amplifiers
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2001This paper compares the main performance parameters of the current feedback opamp (CFOA) with those of a conventional voltage opamp (VOA). To make the comparison effective, a folded cascode VOA is considered (which is characterized by similar features and topology) and the same power consumption was assumed for both amplifiers.

To provide an operation amplifier which improves power source voltage removal ratios while assuring phase compensation characteristics, and therefore can be realized with a small-scale circuit and low power consumption. SOLUTION: The operation amplifier comprises: a differential amplifier circuit 1; an output amplifier circuit 2 connected in series to ...
