Improving Quality of Time Parameters of Vernier-pulse Time-digital Converters 000_13.pdf

Vernier - pulse time-digital converters (TDC) are used for the conversion of time intervals into the code subnanosecond resolution in many areas of science and technology. Disadvantages include low speed and large dead time of conversion, which are defined directly by the vernier - pulse method behind the basis of their work and the need of the total digital conversion result calculation. Therefore, improving the performance and reducing the dead time of vernier - pulse TDC while maintaining their resolution that can significantly extend the possibility of using TDC data in the problems of time intervals transformation become urgent tasks. The article deals with a method for improving twice the time parameters (decrease in conversion time and, accordingly, the conversion dead time) of vernier-pulse TDC by increasing the period following the pulse-counting sequence of the discrete transformation. Replacing the process of calculating the overall digital result of the conversion in the arithmetic logic unit (ALU) to the logical operation of summation result of the digital conversion with twice the value of the digital result just provides a further reduction of the additional value of the dead time conversion. However, the exclusion of the ALU from the conversion process reduces the additional hardware expenses of vernier-pulse TDC and simplifies the process of determining the conversion result. The possibility of determining the overall digital result of the conversion in the same way and in the vernier-pulse TDC executed without increasing the period of starting pulse-counting sequence at the discrete transformation is shown. The method suggested is recommended for halving the time of transformation and reducing the dead time vernier-pulse TDC double interpolation more than twice, for example, in the universal time slot counter NR5370L manufactured by Hewlett Packard.

Structural Ways to Improve the Quality of Recirculationvernierulse Time-digital Converters 35_13.pdf

The article examines a structural method for increasing twice the speed of the recirculation vernier pulse-time-to-digital converters (TDC) with two operating modes and discrete transformations given less than one nanosecond. In the first mode, the period of the start pulse recirculation is selected higher than the highest duration values of the converted time slot (TS). This mode consists of the fact that the start and the stop pulses of the converted TS are recycled in their respective start and stop recirculators recycling with the periods differing by the value of specified discrete transformations, and the fact that the stop pulse recirculation number is counted from the time it enters the stop-recirculator and until the time the recirculation start- and stop-pulses match. At this, each of the recirculations has the start pulse duration extended to a predetermined value of discrete transformations, and the stop pulse duration remains unchanged. In the second mode, the period of the start pulse recirculation is selected less than the highest duration values of the converted TS, and the whole conversion process is carried out in two stages. At the first stage, the number of recirculations is counted during the TS conversion having the readability equal to the period of the start-pulse recycling, while at the second stage, the number of the stop pulse recirculations is counted with given discrete transformations made from the time it enters the stop- recirculator and recirculated until the time matches the start and stop pulses, allowing you to identify the digital conversion result. And if, during the first stage of transformation recycle start- duration pulse remains unchanged, at the second stage, its duration is extended by the given value of discrete transformations in each of recycles. At the same time, the stop pulse duration remains unchanged in the recycling process. To improve the reliability of the recirculation vernier - conversion TDC pulse at the two modes, a method is provided, wherein the start pulse expansion operations are excluded in each of the recirculations, and the recycling period increases by the predetermined discrete transformation. The article gives examples for the hardware (circuit) implementation of the proposed methods and recommendations for their use.
