Abstract
A system and method are provided for performing a spread spectrum clock generation, where the system includes self-adjusting delay line configured to spread the spectrum of a fixed circuit using a fixed clock frequency and a delay circuit configured to generate an adjustment signal to the delay line by adding or subtracting an addition delay per cycle, therefore causing a shift in the output clock frequency, wherein the amount of shift is proportional to the rate of addition or subtraction of delay.
