Patent Searching and Data


Title:
NOVEL TIME-TO-DIGITAL CONVERTER
Document Type and Number:
WIPO Patent Application WO/2019/210642
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communications and specifically relates to a novel time-to-digital converter, comprising: a polarity detection module; and a time-to-digital conversion module, comprising a digital coding unit, a ring oscillator enabling unit, multiple levels of differential delay units sequentially connected in series to form a closed loop, and multiple trigger units. Each differential delay unit comprises a first input end, a second input end, a first output end, and a second output end. The output of the first output end and that of the second output end of each differential delay unit are complementary differential signals. This significantly improves a mismatch between inverter rising and falling times and trigger sampling and allows signals that enter the trigger units to be signals of complementary phases, thus increasing the linearity of digital conversion.
