Analyzing inductive noise in power grids News & Analysis 9/4/2003 Post a comment In any chip design, large, rapidly changing currents in a circuit block can cause large inductive voltage changes in a low resistance power grid. These voltage changes propagate across the chip with very little attenuation causing timing errors, increased stress in thin gate oxides and, in extreme cases, complete circuit failure. This article from eeDesign.com, by a device physicist and simulation expert, provides designers with an overview of the techniques needed to analyze resistive, inductiv
A disciplined Linear defies downturn News & Analysis 9/1/2003 Post a comment It's no exaggeration to say Linear Technology Corp. has all the bases covered. Name an electronics market" automotive, communications, computing, consumer, industrial, medical, or military" and the supplier of the high-performance analog ICs is there, in many cases with single-source, high-margin products.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
