摘要： A pipeline time-to-digital converter (TDC) is provided. The pipeline TDC includes a plurality of TDC cells. Each of the TDC cells includes a delay unit, an output unit and a determination unit. The delay unit receives a first clock signal and a first reference signal output from a previous stage TDC cell. The delay unit generates sampling phases in a period between a trigger edge of the first reference signal and a trigger edge of the first clock signal, and samples the first clock signal to obtain sampling values in accordance with the sampling phases. The output unit calculates the sampling values for outputting a conversion value. The determination unit uses and analyses the sampling values and the sampling phases for outputting time residue to a next stage TDC cell.
