Smart Design Practices Address EMI/EMC Challenges

To produce more circuit functionality, leading-edge designs rely on high-speed devices, using the latest IC process nodes and advanced package technologies. As the complexity of these electronic products intensifies, constraining EM emissions within dense printed circuit boards (PCB), IC packages and even the IC itself requires careful engineering. With...

A Design of Wideband Folded Dual Monopole Antennas for Wireless Communications

This article proposes a new structure for a wideband antenna, featuring omni-directional radiation characteristics based on a single plane structure that can be used in integrated circuits. The proposed antenna is a folded dual monopole based on a mono...
Nowadays, the information society is rapidly changing. Mobile communications and their technologies are increasingly parts of our daily lives. Mobile communications devices are becoming smaller in order to afford efficient mobility. Antennas, which are used to transmit and receive signals, are also increasingly required to become smaller and lightweight,...

Minimization of Phase Noise in Scaled Device Coupled Mode RF Oscillators

This article describes the impact of device scaling on phase noise in coupled oscillators, which have recently emerged as strong contenders for radio frequency (RF) and mixed-signal applications.
As the frequency band for wireless communication shifts higher and higher, the generation of power efficient, low phase noise, broadband and configurable compact signal sources (oscillators) with low cost has become more and more challenging, due to the frequency limitations of the devices (transistors). The performance of communication systems...

Segmented Magnetic Antennas for Near-field UHF RFID

A simple loop antenna of less-than-resonant size is awkward to match and a resonant antenna contains opposing current flows and makes a poor magnetic antenna. Segmented antennas have been constructed that can operate at resonant diameters while still p...
Conventional radiatively coupled, ultra-high frequency radio-frequency identification (UHF RFID) tags have certain limitations: they are physically large and do not operate well in or close to aqueous fluids. Recently, the use of tags configured to use inductive instead of, or as a supplement to, radiative coupling has been advanced...
