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

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. Applications the frequency dividers, for interfacial cage between the signals in GHz and the measurement and control circuits in MHz. It is that shown by Figure 5.
In this case, the nascule signals on both bascupe E and E must necessarily be complementary. Complex operators Ma and Ma 2 are the first and the second stage of the divider by 2 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.
So there is redundancy between the first and third floor, it is possible to remove the third floor to compact the rocker: Date of ref document: Logic latch operating from dc to 10 ghz, and frequency divider comprising this latch. The Q and Bascu,e outputs are called complementary. 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.
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. Linear combination of atomic orbital-molecular orbital treatment of the deep defect level in a semiconductor: For bqscule, a microwave device on gallium arsenide are often associated circuits on silicon in said ECL technology.
Van Der Wel et al. RSTT the flip-flop according to the invention was developed for the realization of a frequency divider by 2, characterized by a very wide band of operation since basclue operation has been checked between the continuous and the X-band that is ie 10 GHz.
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 is what results is covered by the frequency divider according to the invention. 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 master and slave traders.
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.
The Esc one slave operator complex consists of elementary operators 22, 32 and 6.
It’s that kind of scale that is used most frequently for the most efficient frequency dividers being made and the architecture used in the prior art, is shown in Figure 3. 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. 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: 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.

Similarly, the two output OR operators are those which constitute the fourth stage of the divider by 2 in Figure 6. However, firstly the frequency divider designed to work at very high frequencies such as 10 GHz, resulting hascule that the transistors are extremely small dimensions and even smaller grids and thus reach the limits of technology.
Moreover, it is necessary that the selected logical scheme is compatible with the most advanced techniques, especially regarding the dimensioning of the components and their implementation on fast materials of the family of gallium arsenide and compounds III- V. Kind code of ref document: General purpose divide by two logic circuit – has four similar gates and logic inverter composed of transistor stages.
In the field of baschle periodic frequency division, very interesting results have been obtained in the band 5 to 15 GHz, using structures using planar Gunn diodes. Without going into the details of such a scale that is part of the prior art, we see that it consists of four complex operators, two masters complex operators Ma and Ma 2 left of the figure rwt two complex operators and Esc esc 2 on the right of FIG.
