We presents the design and test results of a picosecond-precision time interval measurement module, integrated as a System-on-Chip in an FPGA device. Implementing a complete measurement instrument of a high precision in one chip with the processing unit gives an opportunity to cut down the size of the final product and to lower its cost. Such approach challenges the constructor with several design...
W artykule opisane są projekt i wyniki badań przetwornika czas-liczba o rozdzielczości 5,3 ps (1 LSB) i zakresie pomiarowym 428 ps. Do przetwarzania czasowo-cyfrowego użyta została metoda kodowania wielokrotnego. Metoda ta umożliwia pokonanie ograniczeń technologicznych współczesnych układów scalonych i uzyskanie wartości rozdzielczości mniejszej niż czas propagacji pojedynczej komórki linii kodującej...
