Serial-to-parallel analog CCD GaAs device

Claim 1

A digital-to-analog conversion system including a storage device adapted for converting signal formats, comprising: a plurality of multiple bit digital-to-analog converters having output conductors, the converters operative for concurrently converting digital data into discrete analog data, such that each of the analog data has a magnitude that represents the weighted value of an input digital datum; a plurality of first storage elements interconnected to form a first linear array having an analog output; and a plurality of second storage elements arranged in a second linear array, the second storage elements having input conductors each one of which is coupled to a different one of the output conductors of the digital-to-analog converters to hold analog data transferred in parallel from the converters, the first storage elements operative for receiving discrete analog data from the second storage elements and continually shifting the analog data along the first linear array in accordance with sequences of clock pulses to provide an analog signal at the output of the first linear array, the second storage elements operative for holding the analog data transferred in parallel from the digital-to-analog converters at the end of each sequence of clock pulses.
