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.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
