Even the simple circuit of Figure 1 seems to be suffering from a low phase margin condition as described in Reference 1 with a sharp resonance at 165MHz. It is important, even in lower speed signal ...

How Stable is your Op Amp or FDA design? One of the most important aspects of any end system design is to understand and improve (if necessary) the nominal phase margin for each stage. Since the early ...
