We present the design, operation and test results of a time-to-digital converter based on multiphase clock and implemented in Kintex-7 FPGA (Xilinx). Proposed solution involves a Vernier delay line constructed with the use of Look-Up Tables and interconnect resources. Taking advantage of rising amount of available interconnect resources in modern FPGA(More)
This paper presents the design, architecture, operation, and test results of a high precision time interval and frequency counter made as a small, portable instrument with USB interface. Thanks to the use of advanced time interpolators integrated in a CMOS chip, the precision (standard deviation) below 35 ps was obtained at measured time interval from 0 to(More)
This paper presents the design, architecture, and operation of a precision time interval and frequency counter made as a small, portable instrument with USB interface. Thanks to the use of advanced time interpolators designed in a CMOS chip, the precision (standard deviation) below 35 ps was obtained at measured time interval from 0 to 200 ms. The frequency(More)
General functional decomposition has important applications in many fields of modern engineering and science. However, it is mainly perceived as a method of logic synthesis for implementation of Boolean functions into FPGA-based architectures. In this paper, an application of functional decomposition in other fields of modern engineering is presented. The(More)
