This paper describes circuit techniques for a 1-V operation Bluetooth PF transceiver in 0.2-/spl mu/m CMOS/SOI. Folded LC-tuned and folded transistor-current-source circuits achieve 1-V operation of the RF transceiver. Tuning circuits and a bias generation circuit for robust transceiver operation are explained.
This paper presents design methodology for CMOS RF-ICs in the 2-GHz bond. After describing RF transceiver architectures, it introduces some low-voltage, low-power CMOS front-end circuits that use an LC-tank folding technique. Finally, it presents a 1-V, 12-mW image-rejection receiver in the 2-GHz band.
We propose a "wide area ubiquitous network" as a highly economical and convenient wireless system for providing a wide variety of services. Its basic feature is "wide coverage using ultra low power consumption terminals," and its specific target is a "5-km cell radius using 10-mW transmission power terminals run on ten--year life batteries."
