FEATURES:
On time and on budget: IP for SOC designs
Commercial functional modules help designers meet schedules and cost objectives, but risks abound.
By Gabe Moretti, Technical Editor
LIN simplifies and standardises in-vehicle
networks
The exponential growth of electronic subsystems within vehicles demands
application-specific topologies that range from the mission-critical to the
mundane. Embodying experience from more complex protocols, LIN tackles low-end applications with a comprehensive design flow methodology.
By David Marsh, Contributing Technical Editor
Hitting their stride: new memory technologies
One next-generation technology is finally on a leading-edge process, another is nearing production after years of development, and a third has its first high-volume customer. The nonvolatile-memory race has, for the first time in a long time, become competitive again.
By Brian Dipert, Technical Editor
LEADING EDGE:
Software simulates LIN/CAN bus systems
Software test cases qualify media messaging systems
Wireless USB aims for lowest data rates
500W Class-D amplifier design
Format-tuned codec, encoder contend for relevance
Network analyser performs multi-port measurements to 8 GHz
I/Q modulator eases 3G designs
Servoamp drive is small, versatile, powerful, and networked
Low-cost circuit simulator
DESIGN IDEAS:
Impedance transformer flags failed fuse
Digital waveform generator provides flexible frequency tuning for sensor measurement
Battery-operated remote-temperature sensor drives 4- to
20-mA current loop
Precision current source is software-programmable
Constant-on-time buck-boost regulator converts a positive input into a negative output
Rainbow LED indicates voltage with color
