Time-to-digit converter based on radiation-tolerant FPGA

Popis výsledku v původním jazyce

Architecture of a time-to-digit converter (TDC) is presented. TDC is an electronic device which measures time of arrival of discrete electronic pulses, with respect to reference time base. Our work on TDC is motivated by its applications in field of long-range laser distance measurement and time synchronization. Unlike earlier time interpolation methods, we have chosen all-digital approach based on pulse propagation through tapped delay line. We do not expect it could outperform recent invention of timeinterpolation using narrow-band filter excitation [1], [2]. However, our approach relies on a standard digital circuitry only. With space applications in mind, we are implementing the TDC into a space qualified, radiation-tolerant field-programmable gate array (FPGA). On top of related works [4] and [5] on all-digital TDCs, delay line, we try to gather more complete information about the sampled pulse. It is done by sampling of whole bit vector, corresponding to all of the delay line ta
