Abstract: An integrated circuit memory cell (10) having a bit line (12), a word line (14) and a cell voltage supply (26) is provided. The integrated circuit memory cell (10) includes a first clock line (34) and a second clock line (36). A first transistor (20) is interconnected to the bit line (12) and the word line (14) for providing access to the memory cell (10). A second transistor (22) is interconnected to the cell voltage supply source (26) and to the first transistor (20) thereby defining a first node (S). The second transistor (22) provides a charging path from the cell voltage supply source (26) to the first node (S). A capacitor (30) is provided and interconnects the first clock line (34) and the second transistor (22). The interconnection between the capacitor (30) and the second transistor (22) defines a second node (K).

Abstract: Analog-to-digital conversion through successive approximation is implemented by means of a charge coupled device. During the conversion process two charges are compared, each comparison yielding one bit of a multi-bit number. By increasing the lesser of the compared charges after each comparison, the need to subtract charge as part of the successive approximation process is eliminated.
