Abstract
The aim of the paper is to discuss in detail the compensation of the current feedback amplifier (CFOA). The approach is suitable for a pencil-and-paper compensation and takes into account both resistive and capacitive feedback. The frequency limitation inside the CFOA and due to a load capacitor are also considered. The feature of the CFOA which can be simply compensated for when it is configured as a differentiator is also exploited. To validate the proposed strategies, Spice simulations were performed on the fundamental CFOA topologies, and some of them are included and discussed in the paper.
