A low-power time-to-digital convertor (TDC) for an application inside vacuum has been implemented based on the Wave Union TDC scheme in a low-cost field-programmable gate array (FPGA) device. Bench top tests have shown that a time measurement resolution better than 30 ps (standard deviation of time differences between two channels) is achieved. Special firmware design practices are taken to...

A 32-channel Time-to-Digital Converter (TDC) was implemented in a general purpose Field-Programmable Gate Array (FPGA). The ﬁne-time calculations are achieved by using the dedicated carry-chain lines. A low latency (30 ns) encoder handles the conversion of the ﬁne time measurement. The coarse counter defines the coarse time stamp. In order to overcome the negative eﬀects of temperature and...
