Abstract
The invention relates to a CTD arrangement comprising an input stage (ETS) which increases each of the input, signal-dependent charge quantities by basic charges (fat zero). In arrangements of this kind, it is endeavored to eliminate the influence of fluctuations in operating voltages upon the d.c. voltage component or d.c. component of the output signal. The invention solves this problem in that a compensation stage (KST) which fully eliminates the added basic charges is inserted into the CTD channel. The sphere of application for the invention includes CTD circuits, and in particular CTD transversal filter circuits.
