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.
EnglishA seventh-order phase equiripple continuous time filter implementing pulse shaping and noise filtering for partial response maximum likelihood (PRML) read channel applications is presented. The 7-50 MHz cutoff frequency, amount of boost, and group-delay slope are programmable via 7-b digital-to-analog converters (DAC's). At 50 MHz fc, power consumption is 70 mW and output swing for 1% distortion is more than 500 mVpp. The transconductance capacitance (Gm-C) filter is built in a 0.7-μm 10-GHz BiCMOS technology
