Some notes on practical FDNR filters

Much work has been seen io the fiterature which is aimed at idealizing tbe frequency response of FDNR filters. This paper addresses other properties of such filters. Presented are: a de&n technique wbicb extends the frequency response of hope&we-scaled fit93 to dc; how to optimize filter dynamic range by proper desii of the FDNR's; and a cookbook pro&ore which simplifies designing FDNR elliptic filters.
