Electromagnetic interference (EMI) is an issue every designer of Ethernet-connected devices has to deal with. Making sure the devices are compliant with or meet the requirements of electromagnetic compatibility (EMC), the process of keeping EMI under control so other nearby devices are not impacted, can be frustrating.
While simulation modeling and other design tools will help achieve 90% of EMC goals, the following additional steps are required to complete the final 10%.
Complete the printed circuit board (PCB) layout.
Components are fully populated on the PCB and…
Miniaturizing unwieldy sensors such as gyroscopes and accelerometers through micro system technology created a completely new class of applications, from dead reckoning in GPS-free locations to image stabilizers in cameras and camcorders.
Battery life is an important ergonomic factor when using mobile devices, since no-one likes to frequently hunt for a mains socket. When designing the devices, efficient use of battery energy must be guaranteed. This requires converters which can switch between buck & boost operations, as the cell voltage of the rechargeable battery and the supply voltage are often very close and sometimes…
The integration of gyroscopes and acceleration sensors has now reached a stage where motion can be processed in a simple and cost-efficient manner in consumer devices. Always looking for promising product advantages, manufacturers are implementing acceleration sensors into mobile phones, digital cameras, TV remote controls or to medical equipment, in order to stand out from the competition.…
