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

Introduction Most of us have experience using a wideband signal injection transformer to introduce a modulation signal into our loop...

What injection resistor value should I use? Is it okay to use a little larger resistor like 30 or 50 ohm instead of 5 ohm (like many app...

Many articles and application notes describe the extraction of phase margin, using a non-invasive technique that extracts the phase...

Does the J2110A Bode Box accept both +12V and -12V power supply at the same time? I saw only one red banana jack and one black banana...

This application note also shows how the phase margin of a linear voltage regulator (LM317) can be measured using the Bode 100 and...

When measuring a circuit or device with our network analyzers, engineers generally inject a signal and believe that the measured results...

My Bode plot doesn’t look right, what am I doing wrong? The most common error made when measuring Bode plots is that the signal is too...
