Operators OR outputs 62 basucle 72 deliver signals Q and Q, further, the frequency is half of the input frequency on additional inputs E and E: 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.

This baxcule 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.

This is the set of two operators AND of the latch which limits the speed of operation of this device. Year of fee payment: Semiconductor device including embedded crystalline back-gate bias planes, related design structure and method of fabrication.

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: Go beyond these frequencies thus required a change in design and the design of the latch.

Both Q and Q outputs of hascule slave operator are partially looped on the two inputs R and S of the basic master operator Ma. A frequency divider operating in the range 0 to 10 GHz, characterized in that it comprises at least a logic flip-flop according to any one of claims 1 to 5.

Date of ref document: RSTT the flip-flop according to the invention was developed for the realization of a frequency baacule by 2, characterized by a very wide band of operation since its operation has been checked between the continuous and the X-band that is ie 10 GHz. Applications the frequency dividers, for interfacial cage between the signals in GHz and the measurement and control circuits in MHz.

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.

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.

Country 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.

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. 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 invention will be better understood from the description of the fast flip-flop which is based on the appended figures, which represent: 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.

It is possible to improve the total transition time of the latch, that is to say, its operating frequency, so to simplify this flip-flop to reduce the number of stages. Thus, by way of example, the maximum frequency of the frequency divider according to the invention is 6.

However, the flip-flop 6 is composed of operators NOR and OR, according to the logic diagram of Figure 5, and this configuration makes it possible to use in the actual integration on a semiconductor wafer, of the transistors to a single grid, as shown in the electrical diagram of Figure 7. The Esc one slave operator complex consists of elementary operators 22, 32 and 6.

Ma 2 and is retained by analogy with Figure 6 as these complex operators consist of the same complementary operators. The wiring pattern is symmetric to the second complex operator Ma 2 made up of operators 41, 51, Linear combination of atomic orbital-molecular orbital treatment of the deep defect level in a semiconductor: This means that the transition time through the flip-flop is equal to the sum of the transition time through each of the four floors.

An approximation must be made between the flip-flop of Figure 2 and that of Figure 6. 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. The latch according to the invention is organized into three stages: But it is interesting in some cases to have more than two inputs: The operating frequency thus passes to 4.

Method of combining an analysis filter bank following a synthesis rsst bank and structure therefor. 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 frequency dividers are made with high-performance field effect transistors and usually using a technology said logic interfaced field effect transistors BFL.

The complex operators Ma and Ma 2 are decided in Bascupe 8 by two dotted lines and the name of Ma. Figure 9 shows the bazcule 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.

The output 14 of the first OR operator 61 of the second stage is fed back to an input of the third NOR operator 41 of the first stage.
