Abstract
Utilizing a plurality of analog to digital converter cells with transfer gates as implemented by large scale integrated circuit techniques incorporating charge coupled device technology, a 16 bit or larger analog to digital converter is achieved. On a single integrated circuit chip, the necessary A/D cells are formed, whereby in each cell gate and charge packet transfer paths allow for the analog to digital conversion. With transfer gates coupling the A/D cells, the multi-bit A/D conversion register is constructed. Digital voltage levels indicative of logic 0's or logic 1's are generated from varying analog charge levels applied.
