Today’s consumer, communication, and computer electronic devices have clocks, communication interfaces, and high-speed signal-conditioning circuits that operate at radio frequencies (RF). Providing ...

This article introduces the CMOS integrated transceiver circuit EM4095 for RFID applications working with transponders at a frequency of typically 125 kHz. The EM4095 is a single-chip RFID reader IC ...

Electronic engineers often spend a lot of time on circuitry and components, as they should; after all, that’s their job. Still, there are cases where that aspect of the project is relatively ...

One of the dreams of makers the world over is to be able to print electronic circuits on more or less any surface using a desktop printer. The great promise is the possibility of having RFID circuits ...

Researchers at the University of Pittsburgh Swanson School of Engineering have made cards that have a type of on and off switch. The NFC or RFID circuits are disconnected when in your wallet, and ...

Engineering researchers have developed a suite of techniques that allow them to create passive radio-frequency identification tags that are 25 percent smaller -- and therefore less expensive.

Active inductors have emerged as a transformative component in CMOS radio frequency (RF) circuit design, effectively replacing traditional passive inductors with active semiconductor networks. By ...
