Frequently used crystal oscillators can be a source of serious problems: they do not always work stably, generate electromagnetic noise, not protected from mechanical shock, and long start-up times from power-up are not always acceptable. If you add growing demands, miniaturization… Continue Reading
This article describes how to measure and suppress interference, arising in the input current of pulse voltage converters. As known, to all pulse converters without exception, as AC / DC, and DC / DC, inherent ripple of output voltage, which arise due to the charge and discharge of the output capacitor in… Continue Reading
Everybody knows, that lithium-ion batteries will degrade over time and lose their original capacity. This is very annoying for users., but beneficial for smartphone sellers, who can sell a new battery to the same device every two years on average. Team of scientists… Continue Reading
The article offers several circuit solutions to improve the performance of batteries.. As you know, most batteries have a fairly low voltage and therefore for normal operation of devices they must be collected in batteries. (AKB) or group. However, due to the spread of parameters when working on a load… Continue Reading
In many applications, cheap stabilizers 78xx family of imperfect. When a large difference between input and output voltage, and a heavy load they lost a lot of energy, It is forcing you to use expensive and occupies a lot of space radiator. Switching Converters 78Rxx conclusions, compatible… Continue Reading
