Steve Sandler of Picotest and Heidi Barnes of Keysight teach this short course on Power Integrity. This is part 1 (~90 min) as presented...

Figure 1. Op amps are often used as unity gain signal buffers, which are not as simple to use as it may appear. The unity-gain op amp...

BROWSER-CLASS PROBE Several companies manufacture and distribute high-frequency TDR probes. These probes are typically designed for very...

The mathematics behind the non-invasive measurement was incorporated into the OMICRON Lab Bode 100 VNA software, sold by Picotest.com,...

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

Some low-dropout regulators (LDOs) use multiple feedback loops to improve output voltage transient response. In many of these cases, some...

Although not quite as accurate as the two-port VNA impedance measurement, the current injection technique has advantages including wide...

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...

We can equate the stability to an equivalent phase margin by assuming the magnitude of the gain vector to be 1 and solving for the Q. In...
