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
