An Intuitive Approach To Understanding Current Feedback Amplifiers An Intuitive Approach To Understanding Current Feedback Amplifiers Application Note October 11, 2004 AN9787.1 Introduction Some designers (especially digital designers doing analog the object is to determine the proper value for these resis- design) are intimidated by current feedback amplifiers tors. When the circuit is configured for non-inverting gain (CFAs), thus they don’t take advantage of the CFA’s superior (Figure 1), the input for the circuit is +IN. This terminal con- frequency perform……
