The invention relates to computing and can be used to construct an analog-to-digital conversion. Gels.

The aim of the invention is to increase reliability by simplifying the converter.

Fig. 1 shows a functional diagram of a voltage to voltage converter; figure 2 - timing diagram of the device.

The voltage converter in the code contains the blocks I and 2 converting the time interval into the code, the voltage converter 3 into the time interval, photodetectors 4-6, element. you are 7 and 8, block 9 delay, element OR 10, element OR-NOT, J1, quantrons 12 and 13, pulses, trigger 18, electronically optical 19, emitter 20 of light, optical harness 21.

In the timing diagram (Fig. 2), the numbers indicate the voltages at the outputs of the respective blocks.

Consider the operation of a device consisting of two time domain conversion units into a code. The input of the voltage converter 3 is time: the interval is supplied by a voltage that is converted into a proportional pulse by duration, through the driver 14, an ele- ment, OR 8 and the driver 16 is supplied to the reset inputs of the quantrons of all time interval-to-code conversion blocks and sets them to zero. In addition, the signal from the output of the driver 14 through the element OR 7 is fed to the input of the installation of the trigger 18 and sets it to the unit state, thus opening the electronic-optical switch 19. This state is the initial state of the device.

While the installation is in the initial state, the pulse of the time interval arrives at the emitter, the body 20, the light of which hits the 53 inputs of all the optical fibers of the optical fibers 21 and propagates along their length. The length of the optical fibers, through which the light enters the excitation inputs of the quantrons 12 is chosen so that the first quantron 12.1 light enters the time 1 after the start of the conversion, the second quantron J2.2 10

through time 2 i-, etc. If the conversion is carried out in the decimal number system (there are nine quantum dots in each discharge), then the light enters the excitation input of the ninth quantum dode 12.9 after 8 ° C, after time 9 the light can reach the photodetector 4. The additional photoreceiver 5 comes into light some time after the start of the conversion. The signal from the output of the photodetector 5 is fed to the reset input of the trigger 18, thereby closing the electron-optical switch 19.

After a time of 9 ", the light hits the photodetector 4, the signal from the output of which is fed to the driver 15, which produces the excitation pulses of the first, not yet the drivers of the excited 13-17 20, quantron

the discharge (conversion unit 2), and when the subsequent quantron is excited, the previous quantron is quenched due to the optical feedback. 25 The impulse that the photoreceiver 4 generates, hit the element OR 7, sets the trigger 18, the signal from the output of which opens the electronic-optical key 19. The device is ready 30 for further transformations.

When an optical signal arrives at the optical input and an electrical signal at the control input, the photodetector 6 generates a signal that is fed to the driver 17, which generates the excitation signal of the next, not yet excitable, quantron of the next bit (conversion unit), and the element OR 8 from the output of the photodetector 6, the noctynaeT signal to the input of the imaging unit 16, which produces a reset pulse, resets the quantrons 13, preparing the conversion unit 2 for further conversion. Subsequent conversion units have a block diagram, the same as conversion unit 2, and work similarly to it.

At the end of the time interval, the signal from the output of the OR-NOT 11 element is fed to the inputs of the excitation resolution of the quantrons 12. When the signal is simultaneously fed to the optical inputs of the quantrons 12 and the signal from the output of the OR-HE element 11 is received, the corresponding quantron of the unit 1 is excited. through block 9 and the item NOT 10 goes to

The first input of the element OR-NE 11, removing the excitation enable signal from the quantum dots 12. In the single state, only one quantum remains in each block of the time interval conversion to the code and the information is presented in the single position code.
