Abstract (en)

[origin: EP1971032A2] The invention discloses a circuit structure of a high performance time-to-digital converter including a delay link loop generating low bit data, a counter generating high bit data and a compensated control source The delay link loop counts low bits and sends a thus-generated signal in a specific cycle to the counter. The counter accumulates a period of the signal in the specific cycle as high bits of the time-to-digital converter. The compensated control source compensates and controls a voltage signal of the delay link loop. The invention has the following advantages: a high measurement precision; a fast processing speed; the connection of the outputs of the latches with the high bit counter can ensure correctness of cycle and carry; the introduction of the compensated control source can ensure consistency of the system; and no high requirement is exerted on the components, and hence the circuit structure is easy to implement.
