New generic method for measuring the time of arrival of an electrical signal

In the field of measurement and more particularly for the detection of events, a high degree of precision in the timing is fundamental. This precision can be obtained by implementing TDC - Time to Digital Converter on computer chips. Different methods are now available to achieve picosecond precision, and now  the challenge  is to achieve picoseconds at a moderate cost.

A solution based on a VHDL code implemented on an FPGA, or software code in post-processing on a computer (or on embedded system) has been developed, showing that we can achieve a very high temporal resolution with a simple and inexpensive implementation.
