(a) Consider the flipflop circuits below: (i) Name the 2 circuits given in the figure. Explain how they are different from each other. a. b. (ii) Choose from the list the input that triggers data to travel to the next flipflop in a counter. A: Input at top NAND gate B: Input at bottom NAND gate C: Clock input clk Q

Electronics What is clocking block. If default skew is not given then when input signal sampled and output signal driven.

(d) In a certain clock generation circuitry, the input range of the PLL is 3MHZ – 6MHZ. If the input clock is 16MHZ. what are the best values for the divider and PLL setting to get 20MHZ at the output of the clock generation circuitry?
