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 proposed bridge has a simple analog design featuring few components and may be implemented inexpensively at any laboratory. Yet, it is characterized by a low input stray capacitance (1 pF in the prototype with margin for improvement) and a very good accuracy, in terms of measurement uncertainty and repeatability: the method of balancing successive readings of the voltage drops across the ‘‘capacitor under test” and a reference resistor uses at best the external voltmeter in terms of measurement accuracy and avoid the need for a voltage reference and related stability issues.
