Power Supply Control from PCB to Chip Core
Jun 30, 2010 | Nur Devnani, Eileen Murray
As silicon technology advances to enable higher density ASICs, the core logic voltage decreases. The lower voltage, in combination with higher current requirements, requires tighter tolerances on the power supplies. The control of the power supplies from the PCB to the die is the subject of this study. A frequency sweep simulation using typical bypass values shows that a discrete package capacitor is not a significant factor in reducing the chip core power supply fluctuation. A small voltage boost at the PCB supply can provide a more economical solution to managing the device supplies....
Recommendations for Installing Flash LEDs on Flex Circuits
Dec 09, 2009 | Shereen Lim
For the mobile market some PCB assemblies have been converted to flex circuit assemblies, in part because flex circuit assembly can be twisted or bent per the application needs. Flex circuits offer the same advantages as conventional printed circuit boards: quality, reliability, and high density....
Considerations for High Speed PCB Track Design in 10Gb/s Serial Data Transmission
Dec 09, 2009 | Steve Bowers and Dr Herbert Lage Applications Engineering Avago Technologies Fiber Optic Products Division
A fundamental evaluation of a variety of approaches for designing a high-speed (10 Gb/s) serial differential electrical channel is examined. The application of the electrical interface has been simulated using HSpice software. It demonstrated how the signal quality could be affected by the use of microstrip versus stripline traces and their associated advantages and disadvantages is discussed. Example XFI channels were assembled from the simulation results to demonstrate viability of the application....
