Analogue delay lines, in the form of charge‐coupled or bucket‐brigade devices, are important network elements that may be used in connection with gain elements and summer–subtractor elements to realize microelectronic filters. This paper establishes invariant lower bounds on the sensitivity of the input–output transfer function to perturbations of the gains and delays of the analogue delay lines. Conventional sensitivity criteria, known as the Worst‐case and Schoeffler criteria, are used to represent the nonideal deviation of the transfer function. It is demonstrated that, insofar as tolerance limitations are concerned, the conventional direct‐form structure (which is extensively employed to realize charge‐coupled‐device filters), is far inferior to the ladder structure.
