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.
EnglishAn inverter-based active feedback CMOS LNA with balun function is within a direct converter receiver. The LNA has three gain stages. The Multi-gated transistor (MGTR) technique is employed to null the third-order distortion of the last two gain stages while complementary configurations are used to compensate second-order nonlinearity in all stages. The complete direct-conversion receiver was fabricated in 28nm CMOS. Measurement results indicate that the integrated receiver provides a minimum NF of 3.4 dB, and a maximum gain of 48.2 dB from 1 to 6 GHz. The in-band and out-of-band IIP3 are-10 dBm and-4 dBm, respectively. The receiver dissipates 22.2 mW at 5 GHz LO frequency and occupies an area of 0.08 mm2.

| Abstract: | An inverter-based active feedback CMOS LNA with balun function is within a direct converter receiver. The LNA has three gain stages. The Multi-gated transistor (MGTR) technique is employed to null the third-order distortion of the last two gain stages while complementary configurations are used to compensate second-order nonlinearity in all stages. The complete direct-conversion receiver was fabricated in 28nm CMOS. Measurement results indicate that the integrated receiver provides a minimum NF of 3.4 dB, and a maximum gain of 48.2 dB from 1 to 6 GHz. The in-band and out-of-band IIP3 are-10 dBm and-4 dBm, respectively. The receiver dissipates 22.2 mW at 5 GHz LO frequency and occupies an area of 0.08 mm2. | |
