As. Korotkov, ACTIVE LADDER FILTER NOISE-ANALYSIS BY MEANS OF CONTINUANTS, IEEE transactions on circuits and systems. 1, Fundamental theory andapplications, 40(8), 1993, pp. 536-537
The method of calculation by means of continuants of active ladder fil
ters noise voltage power spectral density is proposed in this brief. T
he connection between noise properties and sensitivity of the filter t
ransfer function is established.
