ABSTRACT:
The proposed general-purpose, fully-analog device is capable of such functions as auto-correlation, cross-correlation, convolution, transversal filters, etc. at high speeds (one megahertz typical sample rates) with no analog-to-digital or digital-to-analog conversions. The device correlates analog samples in one CCD channel against analog samples in a second CCD channel by means of balanced MOSFET's which multiply the associated voltage samples to give current products that are summed for all multipliers. The two CCD channels include unique floating-clock sensor and buffer circuits which sense the CCD charge samples without affecting the efficiency of their propagation along the CCD shift register. The matched MOSFET multipliers and current summing amplifiers are also uniquely combined in a dual-differential configuration so as to minimize the nondestructive sensing and buffering cells and the matched multiplier cells with the longitudinal dimensions of the CCD, permitting the latter to be small for efficient propagation.
