Abstract:
A circuit includes a set of multiple bit generating cells. One or more adjustable current sources is coupled to introduce perturbations into outputs of the bit generating cells. Based on the perturbations, the outputs of a subset less than all of the bit generating cells are selected, and applied as a control.
