Abstract
A circuit includes a set of multiple bit generating cells. One or more adjustable characterization circuits are coupled to inputs to the bit generating cells to affect the outputs of the bit generating cells. Based on the effect of the characterization circuit(s) on the outputs of the bit generating cells, a subset less than all of the bit generating cells is selected.
