ABSTRACT:
A charge coupled device (CCD) analog shift register in a two-channel serial-parallel-serial (SPS) structure operating in a fast-in/slow-out (FISO) mode for high speed signal acquisition and temporary storage of a plurality of samples. The two CCD arrays are clocked simultaneously, and the input analog signal is demultiplexed to the two arrays. Additional transfer electrodes are provided at the input of one of the arrays, and the other array is provided with a sampling clock which is 180.degree. out of phase with the sampling clock of the first array; two consecutive samples of the input signal are taken during each transfer clock cycle. All signal samples are clocked through the arrays simultaneously and appear at the output at the same time.
