ABSTRACT:
Circuitry for compensating for charge transfer inefficiency related dispersion in analog charge transfer devices (CTD's) is disclosed. In one aspect of the invention the tap weights of a filter are modified in a preselected manner to provide dispersion correction. In a different configuration, a dispersion compensating filter is connected to the input of a charge transfer delay line to provide an initial signal which is the inverse of the total dispersion of the CTD. In a further aspect of the invention regenerators are inserted into a CTD delay line to provide negative feedback to previous stages of the delay line in order to compensate for dispersion.
