CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThis paper presents a fully-integrated CMOS front-end based on a direct conversion architecture for UMTS/802.11b-g and a low-IF at 100kHz for DCS 1800. The two key building blocks are a multi-band low noise amplifier that uses positive feedback to improve its gain and a highly linear mixer. The front-end, integrated in 0.13μm CMOS process, exhibits a minimum noise figure of 5.2dB, a programmable gain that can be varied from 13.5dB to 28.5dB, an IIP3 of more than -7.5dBm and an IIP2 better than 50dBm. The total current consumption is 20mA from a 1.2 V supply.
