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.
EnglishA reference-free, fully digital foreground self-calibration strategy intended to automatically tune the clock frequency of Relaxation Digital to Analog Converters (ReDACs), as demanded for linear operation, is presented in this paper. The effectiveness of the proposed approach is demonstrated by computer simulations on a 10-bit, 2MS/s ReDAC designed in 40nm CMOS and operated from a 600mV power supply voltage. After the proposed calibration, the ReDAC is shown to operate near the optimal clock frequency achieving 0.98 LSB maximum INL, 1.00 LSB maximum DNL and 9.06 ENOB.
