Wireless Design Centre Thinks Twice

Ember’s Cambridge, UK-based IC design facility is set to double in size by the end of 2006, following the announcement of the company’s development partnership with STMicroelectronics on ZigBee projects. Its 11-strong hardware design team has already developed two ICs at the site, including the ZigBee industry’s first single...

Radio Frequency Identification: Evolution of Transponder Circuit Design

A basic RFID system consists of three components: an antenna, a reader and a transponder, commonly called a tag. Tag designs are the most well researched over the years and different designs came about to suit their application in various fields. This ...
Radio frequency identification (RFID) is an area of automatic identification that has quietly been gaining momentum in recent years and is now being seen as a radical means of enhancing data handling processes, complementary in many ways to other data capture technologies such as bar coding. RFID systems involve...

A 2.4 GHz CMOS Transceiver Single-chip RF Front-end for ISM-band Wireless Communications

A 2.4 GHz CMOS transceiver single-chip RF front-end for ISM-band wireless communications is presented. The CMOS RFIC contains a gain-controlled low noise amplifier (LNA), a series-type T/R switch and a power amplifier (PA) with diode linearizers, which...
Due to the fast development of wireless communications, a low cost, high performance, highly integrated technology is needed for system-on-a-chip (SoC) implementations. The CMOS technology provides a good solution for SoC integration. 1 Recent improvements of the standard CMOS process make it possible to implement RF blocks, such as...

UHF RFID and Tag Antenna Scattering, Part II: Theory

In Part II of this work, a numerical solution, using a reasonable estimate for the tag IC impedance, is shown to provide accurate estimates of the scattering effects of tag antennas. A greatly simplified scattering theory for tag arrays is also present...
In Part I of this article, 1 a number of experimental results were presented, suggesting that interactions in arrays of tag antennas play an important role in determining when a UHF RFID tag can be read, even when no other scattering is present in the environment. How can these...
