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

Many new linear devices, including voltage references, voltage regulators and opamps have internal feedback loops, prohibiting...

Many engineers are familiar with the Bode plot as an effective stability assessment method. However, some authors suggest and even teach...

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

As Sandler explains, analysis based on impedance measurements can more thoroughly assess control loop stability than Bode plot...

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

It may come as a surprise to some that a control loop’s Bode plot does not always depict the loop stability and that the output impedance...

Output impedance is the key to testing filter and regulator phase margin, even when the control loop is inaccessible. Many voltage...
