A 910MHz high efficiency RF transceiver for Wireless Body Area Network in medical application is presented in this paper. High energy efficiency transmitter and receiver architectures are proposed. In wireless body sensor network, the transmitter must have higher efficiency compared with the receiver because a large amount of data is sent from sensor node to receiver of the base station and sma...

An ultra low power CMOS transceiver has been designed for a usage in medical implant communication service devices. The FCC regulated MICS band which is 402405 MHz, requires ultra low power transceiver for medical implants. The following section gives a brief description of different sections of transceiver. The schematic and measurement results are included for each sub-block of the transceive...

Unified RF requirements are derived for an UTRA/FDD com-pliant mobile transceiver. Consideration of system issues,multi-mode operation, and interfacing concerns leads to de-tailed receiver and transmitter calculations based on exist-ing UMTS specifications. Finally, compliant and design-compatible transceiver requirements are derived.KeywordsRF Transceiver, UTRA/...

The research of the last ten years has resulted in the attempts towards single chip CMOS RF circuits for Bluetooth, ISM and DECT applications. An overvieuw of the use of CMOS for low-cost integration of a high-end cellular RF transceiver front-end is presented. Some fundamental pitfalls and limitations of RF CMOS are discussed. To circumvent these obstacles the choice of transceiver architectur...

Interference alignment (IA) has recently been used for the transceiver design of the K-user constant MIMO interference channel. Since this system is a coordinated beamforming system and there are other design criteria, it is important to evaluate IA transceiver designs in light of other designs. In this paper, relationships between IA and the MMSE, Max Min SI R, Max Sum Capacity, and Min BER tr...

Trung-Kien Nguyen et al. 33 This paper presents the experimental results of a lowpower low-cost RF transceiver for the 915 MHz band IEEE 802.15.4b standard. Low power and low cost are achieved by optimizing the transceiver architecture and circuit design techniques. The proposed transceiver shares the analog baseband section for both receive and transmit modes to reduce the silicon area. The RF...

This paper describes the construction of a laser transceiver designed specifically for the ARRL 10-GHz-and-Up contest. Earlier versions of this transceiver were presented in Microwave Update Proceedings for 1998 through 2000. This version has been greatly simplified. The previous amplifier incorporated automatic gain control to prevent saturation, which was found unnecessary. Also, the detector...

Power line communications (PLC), thanks to the widespread availability of power line infrastructure, is considered as a low-cost alternative for data transmission. Power lines, however, remain hostile environments for communication signal propagation. In this paper, we propose a new transceiver scheme for orthogonal frequency division multiplexing (OFDM)-based broadband power line communication...

This paper presents a radio-frequency (RF) transceiver fabricated in a UMC RF 0.18 μm CMOS process. The RF transceiver was built to operate at the 5.7 GHz ISM band. The transceiver has a total power consumption of 23 mW and it is intended for the use in each wireless node of a wireless sensor network.
