The solution concerns the connection of a phase frequency detector using two D-type flip-flop circuits, equipped with bi-stable current controllers, where outputs of D-type flip-flop circuits are connected to inputs of gates of a NAND type, whose output is connected to resetting inputs of both positive D-type circuits. The principle of the solution consists of the fact that the output (42) of the first current controller (4), whose control input (41) is connected to output (Q2) of the second D-type flip-flop circuit (2), is connected directly to the integration and filtering component (9). The output (52) of the second current controller (5), whose control input (51) is connected to output (Q1) of the first D-type flip-flop circuit (1), is joined with the current supply (6) in series with an induction component (7) connected through a switching diode (8) to the integration and filtering component (9). The output of the phase frequency detector is taken out of the common point of the switching (8) of the output of the current switch (4) and the integration and filtering component (9).<IMAGE>
