ABSTRACT:
A plurality of charge storage cells, each including first and second storage regions, are provided in a semiconductor substrate. Means are provided responsive to a scanning signal for introducing into each of the cells a respective quantity of charge proportional to a respective sample of an analog signal. Each quantity of charge includes first and second portions of equal value. Each first portion is solely contained in the first storage region of a respective cell and each second portion is contained in the second storage region of a respective cell. Means are provided responsive to the bits of one value of a digital reference word for transferring the first portions of said quantities of charge into the second storage regions in the cells associated with such bits of one value. Means are provided responsive to bits of the other value of the digital reference word for transferring the second portions of said quantities of charge into the first storage regions in the cells associated with such bits of the other value. The charges in all of the cells are transferred concurrently from one storage region to the other and the total net charge transferred to and from the first charge storage regions of all of the cells is sensed on a common conductor overlying all of the first charge storage regions of the cells.
