Transient Load Tester for Time Domain PDN Validation

Power distribution networks (PDNs) delivering power to ICs in a system need to be thoroughly designed and analyzed in order to make sure any voltage fluctuation on the rail is within the tolerance of every IC connected to that rail.  As ICs on the rail draw power, they generate a voltage fluctuation on the rail.  The PDN must have the capacity to supply enough charge such that the resulting voltage drop is less than the maximum voltage drop each IC on the rail can tolerate.  If voltage fluctuations appear outside IC tolerance limits, a slew of problems can surface such as IC damage, failure, or reduced lifespan.

A Design Rule Check List

No matter how well you understand the design principles, and no matter how much experience you have in designing boards, it’s easy for some problems to slip through the cracks because you just forgot to check that feature, or your design is just too big to manually check. This is where a design rule checker comes in.

Bode Plots are Overrated

I’m not saying control loop stability isn’t important, of course it is. I am saying that whether your focus is power supply design, power integrity or mixed-signal, the Bode plot probably isn’t going to provide you with a reliable or optimum solution. Here are five major reasons for saying this...
