Sweep parameters in Harmonic Balance trouble frequency
I have the circuit as shown in Fig.1 below in the attached file,
I want to see the result input power with the Output power,
My problem is :
when I put the frequency of (FF, see the figure1) at(2.4 GHz) I face the message in Figure 2(in attached file)
When I make the frequency (0.1 GHz) or below the sweep is run other than it didn't work.
Please, what can I do?
where is the problem in my sweep?
Help me.
Show me all capacitance and inductance values.
Set Order[1]=31 in HB Analysis Controler.
Sorry me, I can't give you the values of capacitances and inductors, because the circuit in the figure1 is my research paper.
Please, May you guide me what is the problems with the capacitor and inductor?
The convergence problems are generally depended on components' values and model parameters.Don't forget that a simulator is a just calculator.
If you enter some nonsense or "impacting" or "weird" numbers , the calculator will stop.This is the same case.Thet's why component values are absolutely effective on convergence.
Sometimes it helps to install a low-ohm resistor in strategic locations. For instance you have 2 capacitors in series with no resistor in between. So the simulator may have trouble calculating a time constant for one or both caps when it sees 2 in series.
Your circuit is too simplistic to work at 2.4Ghz. There are no Transmission Lines, no parasitic values on L and C values. Not even bypass capacitors at supplies. Before hiding your values of Caps and Inductors as if they hold IP value, you should make your circuit more realistic for a start.
Based on the schematic model block, this is a CMOS integrated circuit, where all dimensions are electrically small.
I think this circuit seems to be Class-E amplifier.
Order[1]=5 in HB Analysis is too few.
