- 1V, 100A supplies: Plugging efficiency leaks
ICs that consume 1V, 100A are just around the corner. Manufacturers of regulator ICs and power semiconductors are busy designing circuits and devices that fulfill that lofty requirement.
Design Features
- Power down for portables
A big battery can mean small market share. Reducing power consumption in your portable digital device is the "green" thing to do, as in money. - Building terabit systems with multiple-gigabit, multiple-channel
transceivers
At line rates beyond 3 Gbps, the on-chip integration of multiple analog-PHY channels is challenging. Digital-PHY multichannel integration is more feasible but is struggling to grow in speed. Are multigigabit, multichannel PHYs possible? - The alias theorems: practical undersampling for expert
engineers
Aliasing, long considered an undesirable artifact of an insufficiently high sampling rate, is in fact a useful tool for lab testing and analysis.
