请教怎样用Hspice写THD?
请教怎样写THD(total harmonic distortion)用Hspice?
fundamental frequency为1k ,FOUR_NCOEFF 为12。
TSTEP=500ns, TSTOP=10ms
下面为我所写Hspice code,不工作。 且不知道怎样放入Four_ncoeff。
.tran 500ns 10ms
.four 1k V(outp, outm)
.four 1k V(pos, neg)
FOUR_NCOEFFNumber of coefficients to be generated from Fourier
analysis of signals specified on .FOUR statement.(From TIspice)
