 11 Jun 2003 18:02 PSPICE and DFT |
|
|
|
I have one question about PSPICE , when I do a simulation of a low pass with switched capacitor ,I have a bad Fourier analysis , the response of a pulse has a bad Amplitude
PSPICE doing a DFT but I cannot fix the sampling period.
So if someone has a idea?

| You can set the minimum time step in the .tran line to a smaller value. Also make the tolerance values smaller.

Put the time print step = 1/ts an multiple number of the sampling frequency (clk). The frequency of the print step must also be an odd multiple of the input frequency (fin).
