Use of CCD in the development of digital logic

Digital logic networks, such as OR, AND, NOT (inverters) EXCLUSIVE OR, NAND, and NOR, are developed using charge coupled devices. Operations such as digital addition; multiplication, subtraction and bit refresh are also developed by the implementation of the CCD 3-input, 2-input, and 4-input adder. Equations which will determine the responsiveness (gain) of the charge sensing amplifier are also developed. Very good correlation was obtained between experimental and theoretical characteristics of the 2-input adder, the CCD digital logic networks and the responsiveness of the charge sensing amplifier.
