Abstract
A circuit includes a random oscillation number generator (RONG) configured to generate first and second pulse signals at first and second RONG outputs. A first counter is coupled to the first RONG output and generates a first count at a first counter output. A second counter is coupled to the second RONG output and generates a second count at a second counter output. A selection circuit is coupled to the first and second counter outputs and to the first and second RONG outputs. A first pulse shaper is connected between the first RONG output and the first counter, and a second pulse shaper is connected between the second RONG output and the second counter.
