Nothing New in Power Integrity?
Raj Nair 3/29/2019 Post a comment
The most common approach to PI management, particularly for droops and other dynamic supply differential variations, is the addition of on-chip decoupling capacitance. Capacitance, local to a load circuit that draws transient supply current, can help fulfill transient charge demand.
Power Integrity for IoT Components
Raj Nair 9/6/2016 2 comments
A prevailing assumption in the industry, EDA in particular, is that IoT chips are less of a challenge. Technology and IP integrated are well known. The chips are not leading edge in the fabrication processes used. Tools that met the needs of prior fabrication processes hence suffice to meet the needs of IoT chips. It is just a matter of designing to the specific application
DVD Variation with Load Vector Delays
Raj Nair 6/14/2016 Post a comment
In the following experiment, we explore DVD variance with another aspect of PDN load currents. Here, we explore the temporal relationship between load vectors: time/phase delays between load maxima.
Non-correlation of Peak Noise and Peak Current

Is a power grid represented with good accuracy as a complicated mesh of resistances? We answer the first part of this exploration – the non-correlation of peak noise with peak current – in this experimental study.
PI Continuum Simulation: Load Modulation
Raj Nair 4/7/2016 Post a comment
How do advanced design changes impact power integrity? This is a question often encountered by power-integrity aware IP block designers. And here is where a front-end analysis environment such as Anasim's PI-FP is most useful.
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
