RF system architectures and circuit techniques for wideband transceivers

This paper addresses design consideration and potential solutions for single-chip CMOS wideband RF transceivers. System architectures are discussed together with their challenges as compared to conventional narrow-band systems. At the circuit level, various wideband design techniques for wideband matching, wideband loading, and wideband frequency tuning range is explored. Finally, detailed design and measurement results of an UWB LNA, an UWB synthesizer, and a wideband VCO is presented.
