Use PSpice To Verify Feedback Amplifier Stability (.PDF Download)

Feb. 11, 2013

Feedback systems have a wide range of applications including different types of amplifiers, signal conditioners, power supplies, and voltage regulators. Obtaining their reliable stability sometimes becomes a serious challenge for engineers, which can be simplified by using a computer simulation. Let’s dig into this task by first looking at a model of a negative feedback amplifier and its gain equation (Fig. 1).
