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 new technique for the compensation of the finite gain in an SC integrator is presented. The technique is effective in a narrow frequency range centered around a specific frequency. The new finite gain compensation technique we present is derived from the basic idea of memorizing the values of the output signal of an SC integrator and using them to predict the operation of the stage in the successive timeslots. The operation is based on the memorization of the effects caused by the finite gain at that frequency and on the use of this information for compensating purposes. The circuits proposed are particularly suited for high-Q high-frequency bandpass filters. The example of a biquad is reported.
