This chapter describes the design of transceiver architectures and circuits suited to frequency-hopping UWB applications. A direct-conversion UWB transceiver for Mode 1 OFDM applications employs three resonant networks and three phase-locked loops. Using a common-gate input stage, the receiver allows direct sharing of the antenna with the transmitter. Designed in 0.13-mu m CMOS technology, the transceiver provides a total gain of 69-73 dB and a noise figure of 6.5-8.4 dB across three bands, and a TX 1-dB compression point of -10 dBm. The circuit consumes 105 mW from a 1.5-V supply. A frequency plan for a full-band transceiver is also described.

A time-interleaved pipeline ADC is designed with the reconfigurable resolution and sampling rate, F s , to accommodate different operation scenarios. The main offset and gain mismatches between for Sub-ADCs are modulated to the frequency of F s /2 by the reference- and opamp-sharing techniques. Fabricated in 90nm CMOS, the 7bit ADC has an ENOB of 6.5 at 1.1GHz sampling rate. The I/Q ADCs totally consume power of 92mW from a 1.3V supply.

The curve of a planar antenna edge is an important parameter which affects the antenna performances. In this study, we propose a new edge curve, characterized by the binomial function, for designing ultrawideband antenna. The effect on the impedance bandwidth through the change with the different order of the binomial function and the gap width between the antenna and ground plane has been investigated and analyzed. The measurement result shows a good agreement with the simulation. Besides, the radiation patterns are omnidirectional in the H plane across the operating bandwidths.

This paper presents the design of UWB transceivers from both system-level and circuit-level perspectives. Following a detailed analysis of the impact of RF imperfections on the performance of the system, we review a number of transceiver and synthesizer architectures that can satisfy the MBOA UWB standard requirements. Next, we describe a new transceiver architecture that accommodates, with three PLLs, the 12 bands specified by the recent MBOA proposal. We also present CMOS circuit techniques for UWB receivers and transmitters and demonstrate a new upconversion path for transmitters that achieves high linearity and low power dissipation. Packaging and testing aspects of the design are also summarized.

A direct-conversion ultra-wideband (UWB) transceiver for Mode 1 OFDM applications employs three resonant networks and three phase-locked loops. Using a common-gate input stage, the receiver allows direct sharing of the antenna with the transmitter. Designed in 0.13-/spl mu/m CMOS technology, the transceiver provides a total gain of 69-73 dB and a noise figure of 6.5-8.4 dB across three bands, and a TX 1-dB compression point of -10 dBm. The circuit consumes 105 mW from a 1.5-V supply.

A direct-conversion UWB transceiver for mode 1 OFDM applications employs three resonant networks and three PLLs. Designed in a 0.13 μm CMOS technology, the transceiver provides a total gain in the range of 69 to 73 dB, an NF in the range of 5.5 to 8.4 dB across three bands, and a TX P1dB of -10 dBm. The circuit consumes 105 mW from a 1.5 V supply.
