ABSTRACT:
A delay line, an analog-to-digital converting device and a load-sensing circuit using the same are provided. The delay line comprises a delay-control terminal, a reset terminal, and n delay cells DCELLx(0<x≦n). The delay cells DCELL1˜DCELLnare connected in series to each other. Each of the delay cells DCELLxis coupled to the delay-control terminal and the reset terminal for transmitting the first level stage by stage between the delay cells according to a delay time decided by the delay-control terminal in a sensing period. The outputs of all delay cells are reset to the second level when the sensing period is finished. The sensing period is decided by the signal from the reset terminal. Wherein, at least an output terminal ty(0<y≦n) of a delay cell DCELLyamong the delay cells DCELL1˜DCELLnused as output terminal of the delay line.
