| Abstract: | In order to use optical coupler more convenient and efficient in circuit design,a mathematical model was proposed for the I-V characteristics of optical couplers.There isn't information about the model currently.From the theoretical analysis for current characteristics of light-emitting diode and phototransistor,the relationship between the input voltage and output current was derived for the commonly used phototransistor optocouplers.Thus the mathematical model of this work pattern was accomplished.Using M... |
