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 ...

Read an introduction to this series in Part 1, and Part 2, which covers noise. This is the third and final part in a series which discusses how to properly test a power supply to ensure it will work ...

Negative feedback is used in voltage regulators, point-of-load (POL) regulators, voltage references, operational amplifiers (op-amps), and other electronic circuits in order to produce an accurate ...

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 ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

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 ...

On my first project as a combustion control engineer, I was responsible for loop checks and for watching the experts tune the system controls. The first loop I tried to tune solo was the drum level ...
