IP strategies proliferate as SoC complexity grows News & Analysis 12/19/2002 Post a comment Merging previously designed circuit blocks into new system-on-chip designs seems like a sound way of controlling the complexity of SoC projects and leveraging the relatively scarce resources of the circuit design community at least on the surface. But reuse of intellectual property (IP) is shaping up as a complex design approach with its own unique characteristics.
Power Play News & Analysis 12/17/2002 Post a comment Power management has become an industry staple as the need to switch and convert different voltage levels and concerns about power consumption have increased. But the power management sector, encompassing parts like regulators, rectifiers, and power transistors, has struggled recently as poor market conditions force suppliers to cut prices and refocus their market strategies.
Is embedded Linux the right answer? News & Analysis 12/13/2002 Post a comment Linux has influenced the strategies of some of the world's biggest software and hardware companies and entered the IT departments of even the most traditional corporations.
Estimating MOSFET switching losses means higher performance buck converters News & Analysis 12/11/2002 2 comments Lower voltages, higher current, and faster load slew rate pose a constant challenge for power supply designers. New-generation MOSFETs, high performance capacitors and new multiphase structures pose new challenges, writes this well-versed engineer.* Distributed power architectures - like Point of Load (POL) designs - will benefit from an understanding of MOSFET switching losses, he points out.
Taking the Frustration Out of Embedded Design News & Analysis 12/11/2002 Post a comment Effective hardware/software co-design tools remain elusive for most embedded-system designers. Xilinx's Rich Sevcik discusses why he thinks emerging FPGA design platforms offer a viable alternative to ASIC-based embedded design.
Tandem RF software programs streamline the design of power amplifiers News & Analysis 12/10/2002 Post a comment Harmonic-balance simulators - used in tandem with synthesis software that builds impedance matching networks -- can speed the design of RF power amplifiers. Engineers at Aerial Facilities in the UK show the steps they took to build a tunable 23-dB LDMOS amplifier with a center frequency in the 400-MHz range.
