Meet Piccolissimo: The World's Smallest Self-powered Controllable Flying Vehicle
01.03.2017 · Articles
Technology tends to move toward the bigger and better, cramming more and more features into a given product. But sometimes, less is more. Robots are often called on to do the jobs that are too dirty or dangerous for humans, such as examining the Fukushima Daiichi nuclear power plant after it experienced multiple meltdowns in the wake of a tsunami...

Choosing a Precision Op Amp? Trust Goldilocks
28.02.2017 · Articles
Choosing the appropriate bandwidth for an application of a precision op amp is a lot like the experience of Goldilocks trying to choose between the three bears’ bowls of porridge – one bowl was too hot, one bowl was too cold, and one was just right...
Intersil Announces Industry's Smallest Isolated RS-485 Transceiver
28.02.2017 · News
Intersil Corporation announced the industry's smallest isolated RS-485 differential bus transceiver designed to provide 4 Mbps bidirectional data transmission for Industrial Internet of Things networks. The high-speed ISL32704E delivers industry-leading electromagnetic interference and common-mode transient immunity in a small 4 mm × 5 mm QSOP package that is 70% smaller than competitive devices...

How to measure capacity versus bias voltage on MLCCs
26.02.2017 · Circuits
High-capacity, multilayer ceramic capacitors have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon is present in all high-dielectric constant, or Class II capacitors. However, the amount of variation can differ considerably among different MLCC types...
Crystal orientation a breakthrough for solar tech
26.02.2017 · Articles
Researchers from Los Alamos National Laboratory, Northwestern University and Rice University have tweaked their crystal production method and developed a type of two-dimensional layered perovskite with outstanding stability and more than triple the material’s previous power conversion efficiency, in a step that could bring perovskite crystals closer to use in the burgeoning solar power industry...
