Question
Can we define model parameters of resistor, inductor and capacitor in OSCAD and how to change the operating temperature?

Answers:

There is no separate model for resistor, inductor and capacitor and only you can change is their values like resistance, capacitance and inductance. Pls share the example you are trying to solve. We can work on it.

<a href="https://docs.google.com/file/d/0B9lSgysdbrbAc0xhNFBBS1FTTnc/edit" target="" title="example 4.5">example 4.5</a> This example has been solved using PSpice where components LMOD, CMOD and RMOD are used to define model parameters of the passive components sir. I wanted to know if Oscad too has that feature.

Right now we don't have it. But, we are working on new version of Oscad and we will surely include this facility there. Thankyou for pointing out this.

Thank you sir.

Yes. you can model resistors and capacitors in Ngspice. The problem is that the KiCad to Ngspice converter currently does not support this feature. So you cannot give these parameters from the schematic editor. Please see http://ngspice.sourceforge.net/docs/ngspice-manual.pdf - Ngspice manual pg. no. 65 - 71 to see how a resistor/capacitor can be modelled in the Ngspice netlist. For the time being, you can add these lines to the .cir.out file that is generated by Oscad. See if this can help you produce the waveform given in the textbook. Also mention the changes you have done to the netlist once you submit your codes.
