Understand Analog/Mixed-Signal Design In The Analog And Digital Domains

By Ian Bower, May 23, 2012

TI's Ian Bower looks at the differences between implenting analog and mixed-signal functionality hardware and firmware with the goalof helping designers in one domain comfortable when working with designers in the other.

Unified DDR3 Memory Channel Design for High Bandwidth Apps with Legacy Components

By Chao-Yu Chen, May 22, 2012

Some legacy designs use a non-split transaction type bus protocol DDR3 memory channel. This design unifies the channel design so SoC designers do not have to create separate memory channels to prevent the non-split transaction.

Optimised IPM Spawns Energy-Efficient Motors

By Alberto Guerra, May 09, 2012

Traditional interior permanent magnet (IPM) solutions for the 30W to 200W inverterised motor-drive market require either a large construction or use of an external heatsink. International Rectifier's alternative approach uses PCB copper traces to dissipate heat from the module. As a result, it has a smaller package design and can eliminate an external heatsink.
