In recent years, brushless DC [BLDC] motor control has been gaining traction in markets where improvements in battery life are required, such as cordless power tools. This is largely being driven by demand for increased efficiency, lower noise, and higher reliability. Just a short time ago, BLDC motors used in high performance...

Motion processing is emerging as the only solution that can deliver a new user interface and experience that will make a specific mobile handset stand out.
There is a need for full, six degrees of freedom (6-DoF) motion processing that can precisely translate human motion for the various applications. ...
Beside the common advantages of a flyback converter, it has inherently parasitic components, which typically produce ringing waveforms with considerably high voltage spikes. This ringing can also influence the EMI emissions adversely. Therefore, it is an important task to adequate suppress and damp the ringing effect....

Every year, we waste enormous amounts of food – estimated at 1.6 billion tons annually according to Boston Consulting Group. There are many causes for these losses, but one significant problem is refrigeration failings: in the supply chain, in food production outlets, and in retail stores.
Advantech’s...

This introduction to EPAD MOSFET describes a broad selection of devices with precisely set gate threshold voltage values, including zero threshold made, enhancement mode and depletion mode. Furthermore, novel circuit designs are presented to illustrate how these devices can be used at a practical level. The brief circuit...
In the not too distance past, procuring a low phase noise 1 GHz source was very expensive, limiting it to only very high-end applications that could support the cost of incorporating this technology in the design.
Employing a compact, low-phase noise, high-frequency source in your design will combine the best attributes...
Most often capacitor selection to the uniformed seems like a simple choice but the demands, challenges and expectations of modern electronics prove otherwise. As more electronic systems continue to be integrated into our automobiles, the need for capacitor technologies that deliver high reliability, long life, stable performance,...
Feed-forward headsets typically are more easily developed because the design engineer usually does not have to deal with stability issues. A major drawback of this topology, however, is wind noise, since the ANC microphones are directly exposed to the ambient. An alternative that overcomes this drawback is the use of a...
Modern power distribution systems often contain multiple power sources integrated within one system. A simple variant may be the common double-ended substation, which can be further complicated by additional emergency or alternate sources. This presents significant complexity to the designer attempting to design a protection...
Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces...

Flash memory is commonly used to store firmware in embedded systems. Occasionally, the firmware stored in the Flash memory in some systems is accidentally corrupted, preventing the system from booting up after power-on. Flash corruption is commonly associated with a software bug. However, it is also commonly understood...
Temperature measurement, current monitoring, power supply sequencing, fan control and fault logging are typical board control functions used in complex circuit designs. System designers are faced with continual pressure to meet their development schedules, and need to implement control functions with minimal effort and...
This webinar is intended for engineers working on the design and testing of RF and microwave devices and applications. An analog signal generator must meet several challenging requirements, including signal purity and a precise output power. Since the signal generator is usually not the only device in the signal chain...
