Power Integrity

RSS

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.

DesignCon has been a tremendous source of information for myself and for the team I have been working with at SUN Microsystems, which later became part of Oracle Corporation. This summary is an attempt to capture some of the most influential papers from the past twenty years that made the biggest impact on our work.

This article presents a method for power integrity analysis in FPGA systems by configuring the FPGA to function as a vector network analyzer (VNA) test instrument for its own power distribution network (PDN).

It’s what you don’t know you don’t know that can ruin your day. This paper notes in detailed examples that with today’s high-speed designs, we can no longer restrict our thinking in terms of signal integrity, power integrity or EMC alone. We must consider all three disciplines and become educated about each of them to achieve successful designs.

Picotest.com, has released a new solid-state Semi-Floating Amplifier (SFA), or ground loop isolator, that provides the BEST isolation for low impedance measurements. The new amplifier eliminates the DC ground loop from DC up to 800MHz.

Analog Devices, Inc. today introduced a precision integrated analog front end, controller, and pulse-width modulator (PWM) for battery testing and formation capable of increasing system accuracy and efficiency in lithium-ion battery formation and grading.

How do you design power for sensitive circuits including LNAs, clocks, and PLL circuits? Although these circuits consume low power, they are sensitive to even very low levels of power rail noise. This EDI CON USA 2017 Outstanind Paper Award wining paper discusses the various noise paths that contribute to the degradation of the sensitive circuit as well as how to optimize, measure, and troubleshoot power supply related noise for these applications.
