Abstract
A method for building a simulation program with integrated circuit emphasis (SPICE) circuit model of an optical coupler is provided. The method includes: providing a plurality of electrical parameters of the SPICE circuit model of the optical coupler circuit for a plurality of temperature values, and building the SPICE circuit model of the optical coupler at each of the temperature values according to the electrical parameters of the optical coupler for each of the temperature values, so as to form a plurality of temperature-independent SPICE circuit models of the optical coupler; forming a plurality of temperature-voltage conversion switch circuit elements by utilizing control of a voltage source and temperature characteristics of an impedance; and connecting the temperature-voltage conversion switch circuit elements to the temperature-independent SPICE circuit models of the optical coupler, respectively, so as to build a temperature characterized SPICE circuit model of the optical coupler.
