TINA-TI Free Simulator Tool Make Amplifier Sims Easy

I am attempting to import a spice macro into Tina-TI Version 9.3.30.248 SF-TI, it gives me the following error

Undefined model: C.(C:\program Files\DesignSoft\Tina 9 - TI\EXAMPLES\SPICE\TSPICE.LIB)

I did the compile test as shown in the TINA-TI documentation before creating the part and the model passed.

The model is the BF908 dual gate mosfet from NXP. The model is available from the following link

www.nxp.com/.../BF908.html

Any assistance would be appreciated.

Ramanathan, I'm not sure why you can't get a 110VDC source - I tried it a couple different ways and it worked for me. There are some PMOS models in TINA-TI which simulate fine as well. If you want to post more details about what you're trying to do, even the TINA schematic if possible, in the Simulation forum (www.ti.com/e2e-simulation), we could look into this further for you.

Also, you all might be interested to learn that we just updated TINA-TI to version 9.1 - this brings speed improvements and allows for you to import models from any vendor in PSPICE formats. Check it out at www.ti.com/tina-ti.

hi, i also used TINA. but i cant simulate my required model. for example i need 110volt dc supply. but tina cant do it. also i cant simulate P-type mosfet . can u guide me how can i do it?

Hi Vikas,

Overdrive voltages, gate and drive capacitances etc are provided for standalone MOSFETs. For other devices, the information is at a macro level so that level of detail is not provided.

Other sources of spice models may work but it must be human readable and cannot encrypted. TINA does however handle TINA encyrpted,

Hi Peter,

Noise analysis is device/model dependent - if it was noise optimized then the information would be accurate. Our modelling team is checking on the OPA4820 - I'll get back to you.

Best,

I am using TINA right now. I have breadboarded a circuit (two stages of OPA4820) that is too noisy to use. I also did some TINA noise analysis. I don't think the two are in the same ballpark. Is there a way i can look at the amplitude of the actual output and relate it to some TINA noise analysis. I'm thinking I have something wrong with my breadboard.

Thanks

Pete

This seems to be interesting.

Though I haven't tried it yet (comfortable with spice :)), I was wondering if this can provide the overdrive voltages, gate and drain capacitances and such other details.

One more question, is it compatible with different models that we might want to use from another vendor?
