Abstract :
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.
