Abstract

Time-to-digital converters (TDCs) are highly demanded in digital PLLs, ADCs and time-of-flight measurement units, which are widely used for nuclear instrumentation. Demonstrating applications can be found in the ATLAS detector at the Large Hadron Collider (LHC), or in an accelerator driven system (ADS) like MYRRHA: in the spallation target the position of the liquid lead-bismuth free surface has to be monitored by a light detection and ranging system (LIDAR), which consists of two receiver frontend channels and a TDC. In order to be able to sense a distance difference of 1 millimeter, a TDC with a time resolution of 6.7ps is required. A 1.7mW 5.6ps third-order noise-shaping delta-sigma TDC for time-of-flight measurement is implemented in 0.13µm CMOS. A gamma-dose assessment up to 5MGy proves its radiation hardness.
