HIGH-SPEED HIGH REPETITION RATE DIGITIZER

AN INNOVATIVE TECHNIQUE IS PROPOSED TO ACQUIRE AND DIGITIZE 200 SAMPLES OF DATA TO 8-BIT ACCURACY AT LNS INTER VALS EVERY 67 MS. A UNIQUE CHARGE- COUPLED DEVICE (CCD) S SAMPLES THE DATA AND TEMPORARILY STORES 200 SAMPLES AT 1 GS/S. AT SLOWER RATE, THIS SAME CCD CONVERTS THE 200 SAMPLESOF SAMPLED-ANALOG DATA TO A DIGITAL FORM COMPATIBLE WITH CONVENTIONAL MICROPROCESSORS AND DITITAL MEMORY. IT CAN ACQUIRE AND CONVERT 200 SAMPLES OF DATA AT A 15 KHZ REPET ACQUIRE AND CONVERT 200 SAMPLES OF DATA AT A 15 KHZ REPETIT ION RATE. SIZE, WEIGHT, AND POWER ARE MINIMIZED BECAUSE THISTECHNIQUE MINIMIZES HIGHER SPEED CIRCUITRY. THE RESULTING SYSTEM IS WELL SUITED AS A HIGH-PERFORMANCE ELEMENT OF TACT ICAL MILITARY ELECTRO-OPTIC SCANNERS AND RADARS. IT CAN ALSOIMPROVE THE PERFORMANCE OF FUTURE COMMERCIAL DIGITAL OSCILLOSCOPES AND WAVEFORM RECORDERS.
