Most power supplies and regulators are designed to maintain a constant voltage over a specified current range. They are essentially...

In this application note, we will show you the basic principles for making this stability measurement and how to use these instruments to...

Control loop stability is critically important. But whether your focus is on power supply design, power integrity, or mixed-signal power...

Figure 1. Op amps are often used as unity gain signal buffers, which are not as simple to use as it may appear. The unity-gain op amp...

In 1938 Hendrik Wade Bode, who worked at Bell Labs, published his asymptotic assessment of phase margin and gain margin, bearing his name...

Some low-dropout regulators (LDOs) use multiple feedback loops to improve output voltage transient response. In many of these cases, some...

In this 5-minute video presentation, Steve Sandler discusses how stability impacts circuit performance, offering examples that...

We can equate the stability to an equivalent phase margin by assuming the magnitude of the gain vector to be 1 and solving for the Q. In...

Fortunately, a new technique permits non-invasive stability testing of such devices.1 Designers can evaluate stability by measuring (on...
