The invention discloses a design method of a Geiger mode angular position digitizer (APD) passive quenching and recovering integrated circuit. Based on actual measurement characteristics of a target APD, the invention abstracts an I-V relation, thereby establishing a nonlinear module for expressing the actual measurement characteristics of the target APD. Meanwhile, a fluidic switch is added in adesign process for judging the snowslide quenching time and controlling the snowslide quenching process, and the problem that whole nonlinear I-V characteristics and dynamic conducting resistances ofthe target APD can not fully considered so that the snowslide quenching time can not be accurately judged in the traditional design is solved, thereby improving the design precision and the design efficiency of the Geiger mode APD passive quenching and recovering integrated circuit, enhancing the success ratio of the passive quenching and recovering integrated circuit, and lowering the design cost and the manufacture cost.
