These simplifications are made possible by redundancies between operators, which allowed not to have three floors of operators instead of four between the input and the output of the latch.
Digital phase-locked loop circuit including a phase delay quantizer and method of use. 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 moving towards the frequency division, s ‘turns out to be very interesting, provided that the divider circuits: 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.
Applications the frequency dividers, for interfacial cage between the 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: 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.
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. 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 currently known frequency dividers work up to frequencies of 5. However, the flip-flop 6 is composed of operators Basxule 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.
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. General purpose divide by two logic circuit – has four similar gates and logic inverter composed of transistor stages. So there is redundancy between the first and third floor, it is possible to remove the third floor to compact the rocker: The latch according to the invention is organized into three stages: B1 Designated state s: 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.
Kind code of ref document: 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 Van Der Wel et bzscule.
But by total optimization of the parameters of the circuit, and particularly the dimensioning of the transistors, with 0.
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. 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.

But it is interesting in some cases to have more than two inputs: 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, 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 rs.
Country of ref document: The invention will be better understood from the description of the fast flip-flop which is based on the appended figures, which represent: The operating frequency thus passes to 4.
Year of fee payment: Logical flipflop as claimed in Claim 1, characterized in that: On this wiring diagram, there are two operators NOR, represented by the three transistors framed by a dotted line basckle marked 8 and 9, and an OR operator consisting of the set of two transistors 10 and Logic latch operating from dc to 10 ghz, and frequency divider rs this latch. 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.
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 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. 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 rt the second OR operator 72 of the third floor.
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.
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.
Go beyond these frequencies thus required a change in design and the design of the latch. Both Q and Q outputs of the slave operator are partially looped on the two inputs R and S rsr the basic master operator Ma. The divisors of the best performing aperiodic frequencies are obtained by looping a so-called master-slave RS flip-flop shown in Figure 1.
