“…Upon the release of the 3.1-10.6 GHz band for unlicensed UWB radio operation by the FCC, there has been a variety of coherent signaling techniques [1] and coffesponding transceiver architectures [2], [3] to utilize this available bandwidth for implementing high data-rate wireless personal area network radios. This paper describes a complete UWB receiver designed and integrated as a three chip and planar antenna solution, demonstrating 100 Mb/s wireless reception.…”

A complete 3.1-10.6 GHz ultra-wideband receiver using 500 MHz-wide sub-banded binary phase shift keyed (BPSK) pulses has been specified, designed and integrated as a three chip and planar antenna solution. The system includes a custom designed 3.1-10.6 GHz planar antenna, direct-conversion RF front-end, 500 MS/s analog to digital converters, and a parallelized digital back-end for signal detection and demodulation. A 100 Mb/s wireless link has been established with this chipset. A bit-error-rate (BER) of 10-3 was recorded at -80 dBm at a rate of 100 Mb/s for properly acquired packets in the lowest frequency band. Bit-scaling of the ADC from 1 to 5 bits reveals a 4 dB improvement in the link budget.

“…There are three major UWB systems; direct sequence spread spectrum (DSSS), orthogonal frequency-division multiplexing (OFDM), and impulse radio (IR) [3][4][5][6][7]. Among them, the UWB-IR systems are the simplest, offering low power consumption and a small chip area.…”

A fully integrated UWB-IR (ultra-wideband impulseradio) transceiver was developed for wireless body area networks. The transceiver includes all of the components required for the transceiver; a pulse generator and a power amplifier for a transmitter, an analog front-end circuit and analog-to-digital converters for a receiver, a base-band circuit, and a clock generator. The transmitter generates precisely shaped short impulses with a digitally controlled pulse generator. To reduce power consumption, analog circuits are operated intermittently. The most outstanding feature of the receiver is its low sampling frequency for reducing power consumption. The sampling frequency is as low as 32 MHz, which is the same value as the pulse repetition frequency. The prototype transceiver was fabricated in 0.18-μm CMOS process technology. The transmitter satisfies the Federal Communications Commission spectrum mask, and the transceiver achieves -77 and -68 dB sensitivity for 250 and 10 Mbps, respectively.

This work presents a 14-band low-complexity and high-performance synthesizer architecture for multiband orthogonal frequency-division multiplexing operating in the range of 3.1 to 10.6 GHz. The synthesizer uses a single phase-locked loop with trivial divide-by-2 circuits, single side band mixers, low-complexity filters, and multiplexers. Specifications of the synthesizer components are chosen in order to minimize the total spurs power and respect the IEEE802.15.3a recommendations.Index Terms-Frequency synthesizer, multiband orthogonal frequency-division multiplexing(MB-OFDM), single side band (SSB) mixer, ultra-wideband (UWB).
