Abstract

Fig. 1 shows a standard D-type edge-triggered flip-flop with the standard type of preset and clear. The preset and clear inputs are level sensitive. The design shown in Fig. 2 modifies the standard design by adding the circuitry in the dotted squares. This circuitry transforms the level sensitive clear and preset inputs to edge-sensitive inputs. The block diagram of the circuit shown in Fig. 2 is shown in Fig. 3.
