Abstract
A serial-to-parallel analog CCD GaAs device provides high speed A/D or D/A conversion. A high speed analog signal is sampled by shifting the analog data serially into 'n' CCD elements. Then a parallel load pulse transfers the analog data into multiple CCD holding elements. A bank of A/D converters converts the analog data. Conversely, the outputs of a bank of D/A converters are loaded in parallel into a serial CCD device of 'n' elements. The serial CCD device is shifted out serially to complete the conversion to an analog signal.
