‣ Master/Slave JK Flip-flop
Each master and slave are consist of JK flip-flop so that it operates same by input value of J and K. Master/Slave flip-flop has the form of slave connecting with output part of master. So output of master influences input of slave. It operates as positive edge clock. It means that whenever clock varies 0 to 1, JK flip-flop is operating. The output Q and QN connect the output part of slave, so slave flip-flop operate as negative edge clock. When clock varies 1 to 0, output comes out. The delay value are 11.5ns and 12.6ns.
