This paper analyzes how the use of an asymmetric clock can be an important solution to reduce the switching noise generated by the global clock, with a very reduced degradation in performances and reliability. The suited sizing of clock generators and the design of asymmetric clock tree cells, show the benefits of the proposed technique, validated through a design example where a 50% of noise reduction is achieved with 10% of loss in operation frequency and no penalty, even saving, in power consumption. |
