Hello, My question is simple, and I think it is a bug: When I use function that is defined by .func statement in capacitor equation Q=func(args), I got the error that there is no such function. But it

With that level of input data, the answer is 'make it about enough'. ====================================================================================== Best wishes John Woodgate OOO-Own Opinions

hello sir, how can i set the total winding in trafo simulation? (flyback transformer)

Most kinds of protection involve both a clamping (shunt) element and one (in series) that limits current. Inductors (which ferrite beads are) are just one particular type of series element.

That's not quite true. As you say, you can define functions and save them in plot.defs. So, for example: .func hFE() {Ic(Q1)/Ib(Q1)} ..allows you to label a plot hFE() - useful in device testjigs.

I didn’t follow the discussion, but allow me to throw in that input protection against HF-transients like electrostatic discharge ?sparks“ often can be achieved by ferrite beads put in serial

Neon bulbs can be used for receiver or audio amplifier input protection, modem input protection...etc. Neon bulbs?cannot handle the power a ceramic gas tube protector or varistor provides but they

mliccione89, I uploaded "TIA_Another-way-to-look-at-it.asc" to the Temp folder.? It might help understand what's happening to the output as the pulsewidth of the photodetector varies. Andy

Chris, You can not display the automatically generated node names on the schematic.? But you can see what they are when viewing the schematic.? Hover your mouse over any node (net).? The node name

Sorry, I meant 0.35/Fc => 4.5ns. -- Regards, Tony

Exactly what do you mean by non-linear? You haven't plotted the response to varying input amplitude. All the information you have is the response to two different input pulse widths. No opamp is going

No, you can see what the node names before simulation are by: View > SPICE Netlist As you say, though, the net names are dynamic unless you explicitly name them. Only explicitly named nets are visible

You always should label nodes if they are being referenced in an equation or within a measure statement. Otherwise, they WILL change. leaving the reference invalid. Those labels are visible on the

You can lable the nets with numbers or letters.? As for them showing up as you mentioned I am not sure about that.

Well, except for net 0, common or ground. That is known as the schematic is built. Jim

Those run-time node and net numbers can vary from run to run, especially after adding a component. AFIK, they are not known until the sim runs. Jim, Oregon Research Electronics

I believe that nodes (or nets) can be user-named, and that curves on an LTSpice plot can also be user-named, but sometimes it would be simplest to use the node numbers assigned by the software during

Thank you Andy. I truly appreciate all of your help. I was able to find an opamp that meets my environmental requirements. However the response seems to be nonlinear. Here is the circuit (

I suspect it was a large data file that slowed mine down. My run times were between 12 and 14 seconds, up from ~200 ms V(B) was what I expected, once I realized what the SIN parameters did! One big

Dave wrote, " Certainly slowed down the entire .TRAN period, though. " That should not have happened.? It should slow it down over only 1 ps of the 10 ms simulation -- so about 0.00000001% of it.
