Abstract:
A split column in an imaging sensor array, said split column comprises:a first plurality of unit cells arranged in a first half-column, each unit cell of said first plurality of unit cells is controllably electrically couplable through a first half-column line to a first sense amplifier; and a second plurality of unit cells arranged in a second half-column, each unit cells of said second plurality of unit cells is controllably electrically couplable through a second half-column line to a second sense amplifier, wherein the number of unit cells in said first half-column is equal to the number of unit cells in said second half-column, and wherein said first half-column line is substantially electrically isolated from said second half-column line, wherein the column capacitance of each half-column of said first half-column and said second half-column is significantly reduced as compared to the column capacitance of a non-split column.
