ABSTRACT:
Operating circuitry for linear charge launching, non-destructive weighting and non-destructive charge sensing for Charge Coupled Devices (CCD) employs electronic integrating circuitry at the input and output node terminals of the CCD. Feedback circuitry within the integrating circuitry aids in linearizing the signals, in eliminating the non-linear capacitance effect of the depletion regions, and in freeing the design from device parameter variations such as electrode area and absolute values of threshold potential and thickness of insulating layer. The circuitry is adaptable to most conventional CCD and is readily made up of conventional resistance and capacitance elements, of conventional comparing circuits such as differential amplifying or signal repeating circuits, and of conventional summing circuitry.
