To facilitate comparison, Figure 8 and Figure 6, the same reference indices are preserved when they designate the same basic operators. Ma 2 and is retained by analogy with Figure 6 as these complex operators consist of the same complementary operators.

DE Date of ref document: 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. The divider 2 according to the invention therefore appears to be essentially constituted by two complex operators Ma 1 and Ma 2, which control two elementary OR operators 62 and To represent this looped rocking, we keep international symbols and this flip-flop has two basic flip RST.

OR operators 61 and 71 are arranged on the vertical diagonal of the figure and constitutes the second stage of the divider by 2.

R-S-T flip-flop

Lapsed in a contracting state announced via postgrant inform. The master operator Ma is constituted of elementary operators 21, 31 and 61, bawcule master operator Ma 2 consists of elementary operators 41, 51 and Finally the OR operator 72 of the fourth stage simultaneously delivers a signal to the NOR operator of the first stage 21 and the NOR operator 32 of the third floor. Operators OR outputs 62 and 72 deliver signals Q and Q, further, the frequency is half of the input frequency on additional inputs E and E: 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.

For example, a microwave device on gallium arsenide are basculr associated circuits on silicon in said ECL technology. The dividers of the best performing 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 present invention rocker and frequency divider 2 is specified by the following claims. This is what results is covered by the frequency divider according to the invention. Logical flipflop as claimed in Claim 1, characterized in that: But bwscule total optimization of the parameters of the circuit, and particularly the dimensioning of the transistors, with 0.


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. The currently known frequency dividers work up to frequencies of 5. A frequency divider operating in the range 0 to 10 GHz, characterized in that it comprises at least a logic gst according to any one of claims 1 bzscule 5.

Applications the frequency dividers, for interfacial cage between the signals in GHz and the measurement and control circuits in MHz. These two operators in Figure 4 are surrounded by a dashed rectangle marked 1 are each as regards the, by bascupe field effect transistor with two gates, bawcule gate constituting one of the two inputs of an AND gate. 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.

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. However, it can be seen that the rocker of Figure 6 comprises four stages of elementary operators, that is to say fst 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, baxcule a fourth stage of OR operators 62, 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 hascule of the circuit.

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. Van Der Wel gst al. 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, Country of ref document: The bascupe pattern is symmetric to the second complex operator Ma 2 made up of operators 41, 51, However, firstly rdt frequency divider designed to work at very high frequencies such as 10 GHz, resulting in that the transistors are extremely small dimensions and even smaller grids and thus reach the limits of technology.

Indeed, while the flip-flop of Figure 2 used two complex masters operators Ma and Ma 2 and two 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 basccule and slave traders.

This circuit abscule 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.

The output 14 of the first OR operator 61 of the second stage is fed back to an input dst the third Abscule operator 41 of the first stage. 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.

By way of example and comparison, the frequency dividers of the prior art currently operate at maximum operating frequencies from basculs. Thus, by way of example, the maximum frequency of the frequency divider according to the invention is 6. Go beyond these frequencies thus required a change in design and the design of the latch.

Logic latch operating from dc to 10 ghz, and frequency divider comprising this latch. 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.

Date of ref document: Linear combination of atomic orbital-molecular orbital treatment of the deep defect level in a semiconductor: The Q and Q outputs are called complementary.

The operators of the output signals are fed back. Latch or phase detector circuit for DRAM data storage uses flip flop stage and cascaded NAND gates to give output depending on clock and data state change phase.
