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.
EnglishThe invention relates to a method and circuit for implementing an impedance associated with a monolithically integrated telephone subscriber circuit connected to a telephone line having a pair of terminals. The circuit consists of a resistor connected serially to one terminal of the telephone line, and a series of current mirror circuits. The current mirror circuits are connected in a closed loop configuration to the one terminal of the telephone line. The current mirror circuits divide, by a predetermined factor, the value of the resistor when a DC or very low frequency signal is input to the telephone circuit.
