Noise 102 By Joshua Israelsohn, Technical Editor
A few more basic concepts, presented in this concluding installment of our two-part series, can get you started thinking about designing for low noise.
Design Features
Slew efficiency plays primary role in op-amp selection By Sameer Vuyyuru, Intersil Corp
The selection of high-speed op amps involves judicious trade-offs among the myriad specifications of more than 300 available products. The most important spec to consider is the slew-rate-to-supply-current ratio.
Preserve the quiet in your mixed-signal ASIC By Carl B Falcon, AMI Semiconductor
A general understanding of how system-on-chip designs create and transmit noise and how to keep noise from affecting sensitive circuits can go a long way toward attaining first-pass success.
The slow road to 10-Gbps Ethernet By Bill Woodruff, BitBlitz Communications
Lower speeds don't usually equate with innovation. But in the realm of 10-Gbps Ethernet, two "low-speed" interconnect standards, LX4 and CX4, are reducing implementation cost and enabling new applications.
Sense dc current from the high side By Arlie Stonestreet II, ICE Corp
Although rail-to-rail operational amplifiers are now an accepted way to sense high-side dc current, a dependable circuit requires meticulous analysis and design.
Plug in: Safeguard ac powerline quality By David Marsh, Contributing Editor
Today's proliferation of electronics creates power-quality problems that are sufficiently severe to attract regulatory action.
Positive prognosis By Robert Cravotta, Technical Editor
Electronics is transforming health care, making diagnostics, monitoring, and medical procedures more distributed.
