Circuit Graph

The circuit is an interconnection of a J-K latch and an S-R flip-flop in master-slave configuration. This results to a negative-edge-triggered master-slave J-K flip-flop. The 100 kΩ load resistors are not part of the Master-Slave J-K Flip-Flop, their purpose is to help initialize the output to known logic state. If simulation is started with clock (CLK) at low state, Q and not Q will be at undetermined state and this cannot be exited. If simulation is started with clock (CLK) at high state, Q and NOTQ will toggle regardless of the state of J and K. This can be exited by setting J and K at opposing states and setting CLK back to low. If the clock is set low with both J and K high, the output will continue to toggle but this can be exited by reclocking with opposing logic states at J and K. On the other hand, if clock is returned low with J=0=K, the undetermined state will persist and this cannot be exited. After initialization the flip-flop will function as tabulated below: NO CHANGE: J=0, K=0 RESET: J=0, K=1 SET: J=1, K=0 TOGGLE: J=1, K=1
