摘要：
In this work, the design of a Time-to-Digital Converter (TDC) for measuring the time-of-flight (ToF) of a radio pulse is described. It consists on two blocks: a time-to-voltage transducer, whose scheme is that of a charge pump, designed using a 0.25 mu m CMOS process, and an incremental first order Sigma-Delta (Sigma Delta) converter. The two blocks are connected together by means of a Sample and Hold Amplifier (SHA). The specifications are: time resolution smaller than 27 ps and range up to 220 ns. The total relative percentage error is less than 3%, if a more than 10 bits Sigma Delta converter is adopted.
