ZigBee technology was developed for special wireless networks where Bluetooth & wi-fi technologies are not showing better results. In wireless personal area networks (PAN) where we need to transmit low data rate information in comparatively large area (10-100 m) [1]. We can use Zigbee transceiver system instead of other technologies. As the functionality of SimpliciTI and Zigbee Technology is s...

Global on-chip data communication is becoming a concern as the gap between transistor speed and interconnect bandwidth increases with CMOS process scaling. In this paper a low-swing transceiver for 10mm long 0.54μm wide on-chip interconnect is presented, which achieves a similar data rate as previous designs (a few Gb/s), but at much lower power than recently published work. Both low static pow...

This paper presents a 1.2V 60GHz zero-IF transceiver fabricated in a 65nm CMOS process with a digital back-end. The chip includes a receiver with 14.7dB gain, a low 5.6dB noise figure, a 60GHz LO distribution tree, a 64GHz static frequency divider, and a direct BPSK modulator operating over the 55-65GHz band at data rates exceeding 3.5Gb/s. The chip consumes 374mW (232mW) from 1.2V (1.0V) and o...

A fully CMOS integrated radio frequency (RF) transceiver for wireless sensor networks in sub-GHz ISMband applications is implemented and measured. The IC is fabricated in 0.18-μm CMOS technology and packaged in LPCC package. The fully monolithic transceiver consists of a receiver, a transmitter and a RF synthesizer with on-chip VCO. The chip fully complies with the IEEE 802.15.4 WPAN standard i...

Spread Spectrum (SPSP) Communication is the theoretical basis of Direct Sequence Spread Spectrum (DSSS) transceiver technology. Spreading code, modulation, demodulation, carrier synchronization and code synchronization in SPSP communications are the core parts of DSSS transceivers. This paper focuses on the code synchronization problem in SPSP communications. A novel code synchronization algori...

This paper describes the successful simulation of a complete transceiver circuit with the new VHDL-AMS standard. The aim was to verify the functionality and connectivity of a complete RF transceiver chip under actual application conditions. The transceiver circuit is dedicated to E-GSM/GPRS standards for mobile phone applications. At such a level of complexity, traditional tools do not allow si...

A Real-time Capacitor Compensation (RCC) scheme is proposed for low power and continuous communication in the wearable inductive coupling transceiver. Since inductance values of wearable inductor vary dynamically with deterioration of its communication characteristics, the inductance value is monitored and its resonance frequency is adjusted by additive parallel/serial capacitors in real time. ...

Digital communication using synchronized chaos is reviewed on the example of an optoelectronic transceiver and a wireless transceiver that utilizes chaotic pulse position modulation. Challenges that arise due to noise and other distortions occurring in the communication channel are pointed out and ways to improve the noise characteristics of the synchronization and to make chaos communication r...

There are an increasing number of applications requiring precise relative position and clock offset information. The Global Positioning System has demonstrated precise and drift free position and timing information using CodeDivision-Multiple-Access (CDMA) spread spectrum technology. This technology is widely used and relatively inexpensive, making it attractive in applications beyond the scope...

This paper describes a linear frequency modulated continuous wave (LFMCW) detector which is designed for a collision avoidance radar. This detector can estimate distance between the detector and pedestrians or vehicles, thereby it will help to reduce the likelihood of traffic accidents. The detector consists of a transceiver and a signal processor. A novel structure based on the intermediate fr...
