Duty cycle of clock
Duty cycle: Duty cycle of a clock is outlined because the fraction of a period of clock throughout which the clock is in lively condition. Responsibility cycle of the clock is generally expressed as being a proportion. For instance, determine underneath reveals a clock possessing an active condition of '1' stays minimal for 2 ns throughout its interval of ten ns. It's, therefore, stated to possess a duty cycle of 20%.How duty cycle impacts timing: Obligation cycle of clock performs an enormous part in timing closure of types. We have to consider next variables linked to duty cycle variation while timing.

50 percent cycle timing paths: If you'll find both equally beneficial and damaging edge-triggered flip-flops within the design and style, obligation cycle on the clock matters quite a bit. For instance, if we have a clock of 100 MHz with 20% obligation cycle; For the timing route from positive edge-triggered flip-flop to detrimental edge-triggered flip-flop, we get only 2 ns for set up timing for positive-to-negative path and eight ns for negative-to-positive route as compared to ten ns for a full cycle route. Nonetheless, in the event the very same clock had duty cycle of 50%, we'd have got five ns to the very same 50 % cycle timng route.
Least pulse width demands: At large frequencies, responsibility cycle matters a great deal. As an example, every sequential factor has requirement of bare minimum pulse width that should arrive at it. When the duty cycle on the clock isn't near 50%, we've been restricted in supplying substantial frequency even when we have been capable of conference timing at even better frequencies. permit us consider an case in point. If the bare minimum pulse width need of a flip-flop is 500 ps, then with 50% responsibility cycle clock, we are able to utilize a clock of one GHz (1 ns clock period of time). However, if we make use of a clock of duty cycle of 20%, we simply cannot make use of a clock higher than 400 MHz.
