Bascule rst pdf

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. Year of fee payment: However, firstly the 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.

For example, a microwave device on gallium arsenide are often associated circuits on silicon in said ECL technology. 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. The Esc one slave operator complex consists of elementary operators 22, 32 and 6. Go beyond these frequencies thus required a change in design and the design of the latch.

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.

Digital phase-locked loop circuit including a phase delay quantizer and method of use. It also relates tst the application of the logic flip-flop to a frequency divider by 2, operating the DC to 10 GHz in frequency, this frequency divider being designed in particular in the form of integrated circuit on gallium arsenide. The second advantage is that the functions OR and NOR are separated, and this advantage will be shown later.

By way of example and comparison, the frequency dividers of the prior art currently operate at maximum operating frequencies from 4. 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. Van Der Wel et al.

Similarly, the two output OR operators are those which rsh the fourth stage of the divider by 2 in Figure 6. OR operators 62 and 72 are disposed on the horizontal diagonal of FIG and constitutes the third stage of the divider by 2. The frequency divider according to the invention, that is to say also the flip-flop which is the basis of the embodiment of a rsf has been designed with a dual purpose.

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. 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 rsh of Figure 6, divided over the drawing by two dotted lines that define the master and slave traders.

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 bsacule two transistors 10 and DE Date of ref document: 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.

Kind code of ref document: To facilitate comparison, Figure 8 and Figure 6, the same reference indices are preserved when they designate the same basic operators. 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. But by total optimization of the parameters of the circuit, and particularly the dimensioning of the transistors, with 0.


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. So there is redundancy between the first and third floor, it is possible to remove the third floor to compact the rocker: The currently known frequency dividers work up to frequencies of 5.

Date of ref document: Finally the OR operator 72 of the fourth stage simultaneously rsf a signal to the NOR operator of the first stage 21 and the NOR operator 32 of the third floor.

R-S-T flip-flop – это Что такое R-S-T flip-flop?

Country of ref document: The complex operators Ma and Ma 2 are decided in Figure 8 by two dotted rsh and the name of Ma. 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.

Similarly, the OR operator of the second stage 71 delivers on its output a signal applied simultaneously NOR operators of the first stage 31 and third stage This is what results is covered by the frequency divider according to the invention. In fact, rs can consider a number of redundancies that can remove elementary operators in the complemented latch of Figure 6. 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: 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 its operation has been checked between the continuous and the X-band that is ie 10 GHz.

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
