Cutting data center energy consumption

The vast arrays of computers around the world consume huge amounts of power. The data centers enabling the Internet exemplify this power usage.

Simplifying the analogue side of digital predistortion

Digital processing power offers several methods to improve the efficiency of base station power amps (PAs). Improvements in PA efficiency lead to significant reduction in the operating expense for cellular service providers.

Learning from windmills and recording studios

Wind turbines are deceptive. There is something pleasing about the clean streamlines of the blades, the spindly looking tower and the steady, seemingly slow rotation pumping out clean power.

Reducing energy use, PCB clutter in portables

With the growing feature lists and performance levels that these systems deliver, there is also a growing need to manage power dissipation in portable electronic systems.

Ensure reliability, stability in high-temp electronics

High-temp electronics is a growing market. Merely surviving in a high-temperature environment is not good enough. To meet demands, engineers also expect predictable performance, with stability and reliability.

CFLs with improved PF

NSK8700 asks: "What is the the switching frequency of CFL inverters and how is this fixed? Can anyone provide a circuit schema for a CFL switcher?"

Biofuel prep

Joller replies: Dry algae factor is the percentage of algae cells in relation with the media where it is cultured, e.g. if the dry algae factor is 50%, one would need 2 kg of wet algae (algae in the media) to get 1 kg of algae cells."

Protecting components from ESD damage effects

Protecting components from the effects of ESD damage begins by knowing how they can be damaged and their level of sensitivity.

Power reference design for the TMS320C6472, 12Vin digital power controllers and LDOs (1x C6472)

This design was created to help those users desiring to design a TMS320C6472 DSP into a system using a nominal input voltage of 12V, having a highly flexible power design.

Supercap charger suits portable, data storage apps

Linear unveils the LTC4425, a two-cell supercapacitor charger that address high peak power, data backup and "dying gasp" needs in portable and data storage applications.
