Hi there.
I'm developing a circuit in PSpice including an Impedance-model, which is simulated within a real and a complex part. Also can be looked like a Resistor and a Capacitor that change values according to varying the frecuency.
So, for example, I have:
@35kHz: R=2000; C=2.27nF or also can be modeled like 0-2000j or |Z|=2000 and Phase=-90º
...
@39kHz: R=1550; C=2.39nF or also can be modeled like 202.32-1536.7j or |Z|=1550 and Phase=-82.5º
and so on, until 45kHz (steps can be from 250Hz).
When I try to insert this behavior into my Schematic, using FTABLE Part, I cannot get the right way to simulate whe whole circuit (the output I get has no-sense).
I know the circuit is well designed because if I put single values of a Resistor and a Capacitor instead of the FTABLE componet, I get a correct output. But that's not a polite solution, because I have many values for these components.
I'm trying to set up the FTABLE like this (Parameters are in Modulus and Phase Expression mode)
row1: 35kHz 2000 -90
row2: 38.5kHz 1650 -86.25
row3: 39kHz 1550 -82.5
row4: 41.750kHz 2100 -88
row5: 45kHz 1800 -90
MAGUNITS=mag
What am I doing wrong? Do I need to change other parameters or settings in the FTABLE setup? Is there other way to do what I'm trying to?
Thank you in advance, any help will be much appreciated.
Regards,
D.
