Since time domain source like Vtsine does not have source impedance, so do they give correct result when source impedance is important?
It will not be correct result impedance matching is important.
To simplify the problem, let say if the impedance is 50 ohm then just place a resistor with 50 ohm in series.
Impendance matching is a difficult thing
Thanks.
I also think source impedance should be included in trans simulation.
It is just in one of my simulations, the results with either a power source(P1tone, of course with source impedance) or a time source + 50 ohms resistor in series are different. It seems that the one with P1tone could be wrong. I have checked all the bias, nothing wrong. Really confused.
So has anybody compared these two cases? Or is there any documentation validating transient simulation with power source?
"V_1Tone" with Series Resistor of 50ohm or "P_1Tone" with Z=50ohm always gives same results as "VtSine" with Series Resistor of 50ohm in Transient Analysis unless you do wrong setting in simulation.
Difference of them are phase.
"V_1Tone" and "P_1Tone" are Cosine Waveform(Oriented for HB Analysis orginally).
On the other hand, "VtSine" is Sine Waveform(Conventional SPICE Compatible).

So if you want to set "V_1Tone" or "P_1Tone" as Sine Waveform, you have to set their phase as -90degree.
