dc.description.abstract | This paper explores the use of reconfigurable Low-Noise Amplifiers (LNAs) for the implementation of CMOS Radio Frequency
(RF) front-ends in the next generation of multi-standard wireless transceivers. Main circuit strategies reported so
far for multi-standard LNAs are reviewed and a novel flexible LNA intended for Beyond-3G RF hand-held terminals is
presented. The proposed LNA circuit consists of a two-stage topology that combines inductive-source degeneration with
PMOS-varactor based tuning network and a programmable load to adapt its performance to different standard specifications
without penalizing the circuit noise and with a reduced number of inductors as compared to previous reported reconfigurable
LNAs. The circuit has been designed in a 90-nm CMOS technology to cope with the requirements of the GSM,
WCDMA, Bluetooth and WLAN (IEEE 802.11b-g) standards. Simulation results, including technology and packaging
parasitics, demonstrate correct operation of the circuit for all the standards under study, featuring NF<2.8dB, S21>13.3dB
and IIP3>10.9dBm, over a 1.85GHz-2.4GHz band, with an adaptive power consumption between 17mW and 22mW from
a 1-V supply voltage. Preliminary experimental measurements are included, showing a correct reconfiguration operation
within the operation band. | es |
