A look at wireless techniques allowing low-power sensors and data acquisition systems to communicate wirelessly inside rotating machines.
Ambient energy sources can represent an uncertain power supply in designs using energy harvesting.
A listing of some of the new products revealed at APEC (Applied Power Electronics Conference and Exposition). Suppliers include Cree, AVX, ON Semi and more.
Lithium-ion batteries have emerged as a common energy-storage device in many energy-harvesting applications.
The low-dropout regulator (LDO) has long been the choice for buck voltage conversion not only where cost is an issue but where noise performance is critical.
Today's system board is proliferated with a variety of power supply regulators. In practice, there are three different types of voltage regulators-linear, switching, and charge pumps.
One of the current drivers for use and management of systems based on sensor input is the Internet of Things.
The I²S (Inter-IC Sound) interface was originally defined for use in CD players more than two decades ago, but has been through many revisions and enhancements, and is now a vital element in any digital system that supports music.
While USB came from the PC world, it is not just a PC phenomenon. Cell phones, cameras, recorders, players, display devices, tuners, and more all use USB connectivity, either as a peripheral, or even as a host. Even picture frames have USB ports.
Many wireless links, such as phones and Wi-Fi, are bi-directional and can even be full duplex. However, many applications exist where transmit only is all that is needed for a given design and application.
More than ever, cameras are becoming a part of the personal and business devices we carry in our pockets.
