Abstract :
The design and the practical implementation of high performance active audio low pass elliptic filters using the FDNR (frequency dependent negative resistance) concept is described. This involves a detailed study of the effects of the non-ideal characteristics of the op-amps and the magnitude scaling factor, on the filter performance
