About the sine voltage source in Spectre

[tony_taoyh]

spectre vsource amplitude

In Spectre, the sine voltage source have the following parameters:
offset, amplitude, AC ampltude, DC amplitude;

What is the difference between: amplitude and AC amplitude?
What is the difference between: offset and DC amplitude?

Is my understanding correct?

(1) amplitude and offset is for TRAN analysis.
(2) AC amplitude is just for AC analysis.
(3) DC amplitude is just for DC analysis.

Thanks a lot.

Best Regards,
Tony

Hi,
For a quite long time I am also thinking in the same way. I tested it also and your assumptions seem to be right.

I want to know it also

your assumptions are correct . but the offset part differes with DC and TRAN analysis .
