Analisi temporale di un D-Pet Flip Flop
1) D-PET Schematic
When Preset is “1” and Clear is first “0” then “1”, the flip-flop starts to store the input values. When Preset is “1” and Clear is “0” the flip flop’s output is “0”.
When Preset and Clear are both “0” the outputs gives an indeterminate value, while when they are both “1” the output is “0”.
When Preset is “0” and Clear is “1” the output is “1”.
