When measuring low impedance with the two-port shunt-through configuration, we potentially create an error due to the resistance of cable braids.  This error can be reduced or eliminated by using appropriate preamplifiers. There are professional preamplifiers on the market that do a great job reducing the cable braid error.  If you want to experiment with your own circuit, this article will help you

In exploring options to demonstrate ringing from reflections in transmission lines, Professor Eric Bogatin gets a greater understanding of debouncing circuits. Read on to see where his investigations led him.

This paper reviews four levels of VRM models that VRM designers, board level interconnect designers, semiconductor designers, and product managers often use to explore design tradeoffs throughout the PDN system. The choice of which one to use involves considering engineers’ levels of expertise and what problems they expect to analyze. Some tradeoffs and relative merits of the models are described.

We usually associate problems with the power distribution network (PDN) as from excess VRM noise, or from transient current draw from the core or I/O drivers. But that’s not the only source of PDN noise. Some failures can arise from dull, boring, mundane problems at DC.

The newly released ANSYS® 19.2 enables customers to solve their most difficult product development challenges faster than ever.

SIJ talked with Martin Stumpf about industry trends, how to foster innovation, and what today’s designers need most from their test equipment.

This spring, Molex and Samtec announced a collaboration on next-generation data center solutions. SIJ caught up with Brian Vicich of Samtec, Inc and Brent Hatfield of Molex to find out what that means for engineers.

SIJ talked with Dave Kohlmeier about industry trends, how to foster innovation, and what today’s EDA customers need most.
