Stability is important in analog and power circuits. Without stability, control loops can run out of control, leaving you with oscillations and other nasty realities. Power supplies, for example, need ...

Steve Sandler explains what every engineer should know about ‘non-invasive’ stability assessments. The non-invasive stability assessment is a method that uses an output impedance measurement to ...

In the electronic field, an oscillator is a circuit capable of producing a self-sustained sinusoidal signal. In a lot of configurations, cranking up the oscillator involves the noise level inherent to ...

How to read Bode plots to assess dynamic control behavior of a power-supply design. Observing Bode plots from an example voltage regulator to observe control-loop speed and stability. This article ...

Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...
