Improve clock duty cycle
WitrynaHalf cycle timing paths: If there are both positive and negative edge-triggered flip-flops in the design, duty cycle of the clock matters a lot.For instance, if we have a clock of 100 MHz with 20% duty cycle; For a timing path from positive edge-triggered flip-flop to negative edge-triggered flip-flop, we get only 2 ns for setup timing for positive-to … Witrynaduty cycle of the clock to reduce the deterministic jitter introduced by the duty-cycle distortion. It extracts the duty-cycle information by a differential duty amplifier detection scheme and corrects the clock distortion by a duty-cycle adjuster through the negative feedback loop. The DCC has improved robustness, correction range and operat-
