3.4 to 4.8 GHz 65 nm CMOS power amplifier for ultra wideband location tracking application in emergency and disaster situations
Résumé
To authors' knowledge, this paper presents the first silicon integrated PA intended for ultra-wideband (UWB) location tracking application in emergency and disaster situations (LAES). In the allocated 3.4 to 4.8 GHz frequency band, the proposed 65 nm CMOS PA provides a 1 dB compression output power and maximum power added efficiency of 17.4 ±0.5 dBm and 24.6 ±2.5 %, respectively, for a supply voltage of Vdd = 4 V. In addition, in the frequency range of interest, it achieves an excellent group delay variation and gain flatness of 75.2 ±15.05 ps and 13.65 ±0.25 dB, respectively. The proposed UWB PA provides the lowest group delay and gain variation, with the highest output power level reported so far.
