Abstract
A current flowing through a voltage line and/or a data line in a column of a tracking circuit is determined. A threshold tracking time delay of the tracking circuit is determined. Based on the determined current handled by the voltage line and/or the data line and the determined threshold tracking time delay, a plurality of columns in the tracking circuit, a number of first cells in each column of the plurality of columns, and a number of second cells in the each column of the plurality of columns are determined.
