description: The subject of the graduate qualification work is: Â«Using FPGAs for determination of time intervals in radiotechnicsÂ».The main object of the study, to which this work is devoted, is TDC, implemented on the basis of a programmable logic integrated circuit manufactured by XILINX of the SPARTAN-3 family (XC3S200A). The purpose of the work is to study ways to implement a TDC device and create its model based on this FPGA. To achieve this goal, an analysis was made of the main parameters of time-measuring systems and existing methods for measuring time intervals.For comparison, we chose the numerical-pulse, nonius, method of charging and discharging a capacitor, as well as the method of digital delay lines. As a result of the comparison, the method of digital delay lines was chosen as the most rational. A comparison was made of the characteristics of microcontrollers and FPGAs, on which it is advisable to create a TDC and concluded that sufficient efficiency at the lowest cost can be achieved using FPGAs. Further, in the development environment EASYEDA, a circuit of a device for determining time intervals was developed and simulated. As a hardware platform for its implementation, the FPGA of the Spartan-3 family was chosen, since this FPGA has all the necessary characteristics and is economically viable. As comparators, we selected 
ADCMP567 operating in the 250 ps range, which provides a sufficient signal comparison speed.Thus, the digital delay line method implemented on the XILINX FPGA from the SPARTAN-3 family (XC3S200A) using the ultra-fast comparators ADCMP567 has several advantages in its high-speed and economic segment compared to other implementations.
