Abstract :
A new design of a time-to-digital converter (TDC) implemented on an FPGA chip with amorphous antifuse structures is presented. Time coding with 200-ps resolution (LSB), 10-ns range, and very short conversion time is realized by two tapped delay lines working in-a differential mode. Thanks to the local feedback loops, the output from the delay line is obtained directly in “1-out-of-N” code and then converted to 6-bit natural binary. Within the temperature range from 0°C to 45°C, the time offset at the output is constant, the resolution changes by ±0.02 LSB, and the offset-corrected integral linearity error is less than 1 LSB
