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 ...

After my last Signal Chain Basics article, The basics of op amp loop-stability analysis: A tale of twin loop-gains, I received questions about how to generate the open-loop SPICE simulation curves ...

Differential amplifier circuits, such as the one illustrated in Figure 1, are required in analogue technology for a wide variety of applications. One example is measurement technology in which, ...
