Meanwhile, the output 12 of the first NOR operator 21 of the first control input of the first OR operator 62 of the third floor, and the output 13 of the second NOR operator 31 of the first stage control input the second OR operator 72 of the third floor. It is therefore necessary to interface the part of the system that works in the microwave generated by circuits on gallium arsenide, and the part of the system that works with circuits made of silicon, and therefore to a division of frequencies to lower GHz to MHz.

In the field of the bzscule frequency division, very interesting results have been obtained in the band 5 to 15 GHz, using structures using planar Gunn diodes. General purpose divide by two logic circuit – has four similar gates and logic inverter composed of transistor stages.

This is what results is covered by the frequency divider according to the invention. Figure 9 shows the circuit diagram of the latch according to the invention and sets of components which constitute elementary operators are surrounded by a dashed line for ease of identification. Since elementary operators NOR third floor in Figure 6 all have parallel functions to those of elementary operators of the first floor, the operators of the third floor were removed, which saves on the overall delay of the circuit.

To divide the frequencies in ranges of 5 to 10 GHz, it is clear that one must have recourse to the most advanced techniques and that these bawcule dividers are made with high-performance field effect transistors and usually using a technology said logic interfaced field effect transistors BFL.

An approximation must be made between the flip-flop of Figure 2 and that of Figure 6. So there is redundancy between the first and third floor, it is possible to remove the third floor to compact the rocker: The Q and Q outputs are called complementary.

OR operators 62 and 72 are disposed on the horizontal diagonal of FIG and constitutes the gst stage of the divider by 2. Similarly, the two output OR operators are those which constitute the fourth stage of the divider by 2 in Figure 6.

Lapsed in a contracting state announced via postgrant inform.

The master operator Ma is constituted of elementary operators 21, 31 and 61, the master operator Ma 2 consists of elementary operators 41, 51 and On this wiring diagram, there are two operators NOR, represented by the three transistors framed by a dotted line and marked 8 and 9, and an OR operator consisting of the set of two transistors 10 and Year of fee payment: The invention will be better understood from the description of the fast flip-flop which is based on the appended figures, which represent: An improvement which allows to double the maximum of a frequency divider in addition to the fact that the master carrier and the slave operator are identical, is to use a clock locking doors, that is to say having a latch RSTT type, wherein T is the complementary signal of the input signal T.

Logical flipflop as claimed in Claim 1, characterized in that: On the one hand, its electric scheme was optimized in order to simplify it, by reducing the number of stages, thus a reduction of the propagation times through the stages and consequently an increase in the maximum operating frequency. The complex operators Ma and Ma 2 are decided in Figure 8 by two dotted lines and the name of Ma.

Actually achieving this feature entirely valid for moderately high frequencies, that is to say until 4 to 5 GHz, is opposed to such operator can operate at higher frequencies.

Country of ref document: Each NOR operator 21 of the input stage attack in parallel an OR operator 61 of the second stage and an OR operator 62 of the output stage. The primary interest of this kind structure is that the transistors used in NOR operators for the inputs labeled A, B, C and D are single-gate transistors, that is to say it will be possible to carry out dimensional grids much smaller corresponding to greater frequencies.

## Logique séquentielle/Mémoires et bascules

The development of microelectronics microwave, that is to say one that is carried out on new materials type gallium arsenide and other materials derived families III-V and II-VI, required the parallel developing means of control and processing microwave signals.

Thus, by way of example, the maximum frequency of the frequency divider according to the invention is 6.

Digital phase-locked loop circuit including a phase delay quantizer and method of use. Logical flipflop as claimed in Claim 1, characterized in that, for each of the four operators of the input stage 21, 31, 41, 51their output signal is sent in parallel to an OR operator of the second stage 61, 71 and to an OR operator of the third stage 62, This circuit is used in the interfaces between the very high frequencies that are measured in GHz and the monitoring or analysis systems operating at lower frequencies that are measured in MHz.

Furthermore, the OR operator 62 of the fourth stage delivers at its output a signal applied in parallel to the NOR operator of the first stage 51 and the NOR operator 42 of the third floor.

Go beyond these baacule thus rwt a change in design and the design of the latch. To represent this looped rocking, we keep international symbols and this flip-flop has two basic flip RST.

Ma 2 and is retained by analogy with Figure 6 as these complex operators consist of the same complementary operators.
