A system includes first and second synchronous circuits and an asynchronous circuit configured to receive input from the first synchronous circuit and to send output to the second synchronous circuit. First and second variable clock generators are configured to drive the first and second synchronous circuit. A delay circuit is configured in a pathway from the first variable clock generator to the second variable clock generator, the delay circuit being configured to add a delay to the pathway based upon a processing time or an expected processing time of the asynchronous circuit. The delay circuit is further configured to induce additional uneven delay into the pathway. The additional uneven delay disperses local current absorption, thereby decreasing overall electro magnetic emissions of the system.
