PI sim needed for LTspice please

[6666]

Hi
just started trying to use this LTspice
would anybody have a simple PI sim they could share please ?
the typical 555, coil, IRF740 fet, first amp is all I really need to try it out

thanks

Don't bother trying to model a 555. Your first sim should have a FET, an ideal square wave driving the gate, and a coil and damping resistor for the load. Then start adding more complexity, like coil capacitance and a realistic gate drive.

Ok thanks Carl, new to this Ltspice thing
will give that a try
cheers

If your still looking for the basic fet circuit with amp I could send one your way, just let me know

this will get you from zero to hero.

Q for Carl... I was thinking about a Quadrature Transmit signal - Would you expect a return to have both components?

Thanks Golfnut
but when I run it I get an error message saying it carnt find the IRF9640 model
guess thats not part of the basic library
will have to try and add it in somehow
cheers

just found the change to new component feature and it runs , thanks GN.

What do you mean by "Quadrature Transmit signal"?

The example you have provided isn't convenient. Please do take some lecture lessons here:
