Cover Story
- Run for your life: Ultralow-power systems designed for the long haul
Systems can achieve an average current drain on the order of 1 μA by relying on a low duty cycle and by minimizing the power needs of their processor, software, and analog interface.
Design Features
- Mixing the real with the virtual
The benefit of real-time hardware-in-the-loop simulation and its falling costs are encouraging a wider audience to adopt the technique. - Embedded-system programmers must learn the fundamentals
Embedded-system programmers can no longer rely on Moore's law. Its diminishing effect on processor performance doesn't conceal inefficient and disorganized code. - Power-system communications support digital-power growth
Power-bus standard enables digitally controlled power management. - Dithering increases dynamic range in digital-radio system
The drive for high-rate, multistage-converter applications, such as digital radio, increases the need for dithering. Techniques are available to help you accomplish your dithering goal. - Motion ICs make their move
Integration is the key with the motion-control IC.
Leading Edge
- FROM EDN EUROPE: SoC hardware debug techniques extended to system-level
- Bluetooth-UWB merger will take time
- Sense resistor’s low TCR ensures consistency
- Processor and tools support dynamic reconfiguration
- Kit eases high-voltage designs
- Silicon and quartz combine for advanced crystal entity
- SMT device painlessly performs 1-GHz splits
- Receiver shoots fiber to TTL at 5 Mbps
- Sign-off power network and EMI-analysis tool decrease delay from voltage drop
Tech Trends
- PCI Express and ASI: avoiding chaos at 2 Gbps
At data rates as high as 2 Gbps per lane, little things can make big differences in signal integrity. Experts disagree on whether thinking about what's really going on can improve performance or only make it worse.
