Device for transforming a type "D" flip-flop into a flip-flop called type "B" able to sample data both on leading and trailing edges of the clock signal
Abstract The present invention is directed to the technical field of discrete electronic components and in particular refers to a circuit device for transforming a type "D" flip-flop into a flip-flop called type "B" able to sample data both on leading and trailing edges of the clock signal, which has a first type "D" flip-flop at whose clock input is electrically connected an exclusive OR,to this first type "D" flip-flop is connected a second "D"-type flip-flop identical to the first one which,being also circuitally connected with the exclusive OR output, allows to realize a flip-flop called type "B" which represents,in the wholly integrated circuital form,a new discrete component which enables various circuital functions not possible or not practically feasible in the prior art.
A circuit device for transforming a type "D" flip- flop into a flip-flop called type "B" able to sample data at its input both on leading and trailing edges of the clock signal,of the type comprising an exclusive OR, whose output is circuitally connected to the clock input of a first type "D" flip-flop and a delay circuit means circuitally connected to the exclusive OR too,said device being characterized in that said delay means consists of a second type "D" flip-flop whose outputs QN,Q are respectively the outputs QN,Q of the flip-flop called type "B",and whose input D is the input B of the flip-flop called type "B", and whose clock input is connected to the exclusive OR,this latter having two inputs,the first one being the clock input of the flip-flop called type "B" and the second one being circuitally connected to the input D of said first type "D" flip-flop which input D,in turn, is short-circuited with the input QN of the same flip-flop.
