Feature demand strains portable memory design Teardown 1/30/2006 Post a comment Handset models are changing every year as designers strive to strike a balance between what end users want and what can actually be designed in. Many trade-offs must be considered, including performance and features vs. price, size and battery life.
Minimizing Servoamplifier-Sourced Noise Design How-To 1/17/2006 Post a comment PWM servo amplifiers energize servo motors with current waveforms under control of fast-rise voltage pulses. The faster the rise rate of the drive pulses, the lower the energy dissipation in the servo amplifier's MOSFET or IGBT power semiconductors, and amplifier efficiencies in 95% region become possible. Unfortunately, there's a rise-rate tradeoff: the faster the rise rate, the more likely is the amplifier to source noise currents that interfere with neighboring circuits.
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
