This paper presents an improved power spectrum mathematical expresstion of several injection signals. Fourier series expansion is used to analyze the power spectrum of different injection pulses,such as sine,triangle and rectangle wave. On the basis of it, the effect of injection pulse on semiconductor devices and currents are discussed in this paper. Calculated results show the power spectrum of rectangle wave is larger than others. The mathematical expresstion of power spectrum can be obtained using the method given in this paper. Moreover, it has the advantage of simple calculation compared with other methods.
