The current high-growth nature of digital communications demands higher speed serial communication circuits. Present day technologies barely manage to keep up with the present need to communicate at high speeds (e.g., gigabit, terabit, and higher transmission speeds). New techniques are needed to ensure that methods for serial communication can continue to expand and grow. A novel approach to high-frequency communications demands on serial communications circuits has been invented. A multi-stage ring oscillator topography has been developed in which each stage is coupled to two or more previous stages output. The advantage of this approach is the increased capacity to achieve higher frequencies than those utilizing the output from only one previous stage. This is accomplished with the same power consumption and with less output noise due to averaging effects.
