Re: Loudspeaker model
Sanzha, in addition to what yoyu can find in the all_fils.htm, this link may give you some info on making your own model. http://www.transparentsound.com/measurements/Tomi_Engdahl.pdf Regards, Steve

Re: Is there any good 8 Ohm 0.5W loudspeaker model?
First, please don't put your question only in the subject line; it needs to be in the message body, like this: Subject: Loudspeaker model Message: Is there any good 8 Ohm 0.5W loudspeaker model? There

Re: Loudspeaker model
sanzha.shabdarov asked if there are SPICE models for loudspeakers. There are. One of the things that you saw when you joined this group (but probably did not pay attention to), is the fact that the

Re: How to include component values in LTSpice trace formulas
Doug, you probably realized this already, but I had completely misunderstood your original question. When you asked about "traces", I thought you meant PCB traces, A.K.A. "wires" or nets. Silly me, I

Loudspeaker model
I am quite new for all of LTSpice stuff, so, I don't know where to search necessary models. Thus, I just wanted to ask does somebody have properly working ltspice model for 8 Ohm 0.5W loudspeaker?

Re: How to include component values in LTSpice trace formulas
Just create a voltage source and assign its value the parameter name. You can now use the voltage of that source in your formula to access the parameter value. If you desire, you can also divide the

Re: How to include component values in LTSpice trace formulas
Thank you, Tony - that's even better than what I was looking / hoping for. I'll be studying what you've done to become more adept at it. I wasn't even aware of the measurement subsystem before, and I

Re: DN3545 N-Channel, Depletion-Mode Mosfet Model Possible in LTSpice?
Hello Donald, Thanks for the pointer. Does this imply that I can turn a suitable enhancement mode N-chan VDMOS into a depletion mode device by just inverting VTO? Sounds so easy ;-) ! Jan Didden

Hello Alan, I just tried again with gshunt to check that it really has been used inside the subcircuit. I got +25% more supply current even with only gshunt=1e-11. The more interesting option is gmin

Thanks guys, I thought this only add to the external circuits, not the inside of the opamp. Now I know. I notice the Ti models don't work as well as the LT models, The LT models don't need to play
