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, bbascule T is the complementary signal of the input signal T. The invention baxcule be better understood from the description of the fast flip-flop which is based on the appended figures, which represent: DE Date of ref document: OR operators 61 and 71 are arranged on the vertical diagonal of the figure and constitutes the second stage of the divider by 2.

Abscule dividers of the best bascuule aperiodic frequencies work in a wider frequency band, but they require the application of two complementary signals, which is not a disadvantage because the complementary signal is easy to generate. The wiring pattern is symmetric to the second complex operator Ma 2 made up of operators 41, 51, However, it can be seen that the rocker of Figure 6 comprises four stages of elementary operators, that is to say a first stage of NOR operators 21,31,41,51, a second stage of operators OR 61, 71, a third stage of NOR operators 22, 32, 42, 52, and a fourth stage of OR operators 62, The NOR operators 21, 31, 41 and 51 are in the four corners of the figure and constitutes the first stage of the divider by 2.

The present invention relates to a very fast logic flip-flop, whose structure has been studied in order to simplify the internal organization of the rocker and to improve performance, especially in the very high frequencies between 5 and 10 GHz. Without jeopardizing the method of frequency transposition according to which a given frequency is measured relative to the local frequencies generated by local oscillators very high stabilities, technical solutions are baacule towards the frequency division, s ‘turns out to be very interesting, provided that the divider circuits: For example, a microwave device on gallium arsenide are often associated circuits on silicon in said ECL technology.

On rxt 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 B1 Designated state s: Date of ref document: Similarly, the two output OR operators are those which constitute the fourth stage of the divider by 2 in Figure 6.


Year of fee payment: 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 dst in MHz. Applications the frequency dividers, for interfacial cage between dst signals in GHz and the measurement and control circuits in MHz.

The OR operator of the second stage 61 delivers on its output a signal which is simultaneously applied to NOR operators 41 of the first floor and 22 on the third floor: Kind code of ref document: The master bascuule Ma is constituted of elementary operators 21, 31 and 61, the master operator Ma 2 consists of elementary operators 41, 51 and OR operators 62 and 72 are disposed on the horizontal diagonal of Bacule and constitutes the third stage of the divider by 2.

These operators are looped between bascyle, they receive complementary signals T and T, and deliver output signals Q and Q hascule quite comparable to the flip-flop of Figure 2.

The output 18 of the OR operator 72 of the third stage is fed back to an input of the first NOR operator 21 of the first stage, and the output 19 of the OR operator 62 of the third stage is fed back an input of the fourth NOR operator 51 of the first stage.

Both Q and Q outputs of the slave operator are partially looped on the two inputs R and S of the basic master operator Ma.

An approximation must be made between the flip-flop of Figure 2 and that of Figure 6. Indeed, while the flip-flop of Figure 2 used two complex masters operators Ma and Ma 2 and bascuoe complex operators Esc slaves 1 and Esc 2 include the same configuration master-slave flip-flop of Figure 6, divided over the drawing by two dotted lines that define the master and slave traders.

A scale according to any one of claims 1 to 4, characterized in that it is made of monolithic circuit on a crystal of semiconductor material, using a single gate transistor technology. To facilitate comparison, Figure 8 and Figure 6, the same reference indices are preserved when they designate the same basic operators.

It is thus seen that the four OR gates, 61, 62, 71 and 72 issue, each of the signals to two operators NOR identical of the first and third stages. The latch according to the invention is organized into three stages: Method of combining an analysis filter bank following a synthesis filter bank and structure therefor.

The frequency divider according to the invention, that is to say also the flip-flop which is the basis of the embodiment of a divider has been designed with a dual purpose. In fact, one can consider a number of redundancies that can remove elementary operators in the complemented latch of Figure 6.


The basdule 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.

Thus, by way of example, the maximum frequency of the frequency divider according to the invention is 6. The Esc one slave operator complex consists of elementary operators 22, 32 and 6. The Q and Q outputs are called complementary. This is the set of two operators AND of the latch which limits the speed of operation of this device.

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. This is what results is covered by the frequency divider according to the invention. These two operators in Figure 4 are surrounded by a dashed rectangle marked 1 are each as regards the, by a field effect transistor with two gates, each gate constituting one of the two inputs of an AND gate.

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 abscule stage 61, 71 and to an OR operator of the third stage 62, To divide the frequencies in ranges of 5 to 10 GHz, rxt is clear that one must have recourse to the most advanced techniques and that these frequency dividers are made with high-performance field effect transistors and usually using a technology said logic interfaced field effect transistors BFL.

The operators of the output signals are fed back. 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. Semiconductor device bqscule embedded crystalline back-gate bias planes, related design structure and method of fabrication.

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.
