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 ...

These three analysis methods are linked together, so this section is organized by control method. In contrast to the large-signal transient response that was reviewed in part 2, we will perform ac ...

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 ...

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 ...
