Hi Andy: I have V(XSW11:X1:Qc,XSW11:X1:Qe) plotted in the plot window. I right-click the V(XSW11:X1:Qc,XSW11:X1:Qe) plot header and cut-n-paste the V(XSW11:X1:Qc,XSW11:X1:Qe) expression from the

Oops, nodenames, not codenames.? Darn auto-correct.

Are you certain that those are the exact, correct codenames nodenames? Did you get them from the expanded netlist, and were you using a version older than 24.x? Andy

Hello All, According to the help file: .MEAS TRAN res2 FIND V(out)*I(Vout) WHEN V(x)=3*V(y) Print the value of the expression V(out)*I(Vout) the first time the condition V(x)=3*V(y) is met. This will

john23, I uploaded AD797_Opamp2.zip to the Temp folder.? It shows the opamp2 symbol, applied to the "MyAD797" (wrapper) subcircuit. Andy

That works too. I was trying to make it work without modifying the original AD797 SPICE model.? Sometimes, IC manufacturers get really picky about altering their SPICE models, and I wanted to avoid

You did not follow what I said to do. What was the point of creating a subcircuit named "MyAD797", if you did not even bother to use that subcircuit? The subcircuit you created (as a "wrapper" around

Hello Andy,I managed to do it as shown in the attached file. added the whole netlist as a directive and deleted the last pin number of the title. Is it Ok? Thanks.

Hello Andy,I did what you said it still gives a netlist bug which says pin mismatch. Ltspice file and the errotr is attached. Where did I go wrong? /g/LTspice/files/Temp/ad797_cir.zip

Group member "flyback" (massey2) uploaded a schematic earlier today "LLC to compare.asc".? ?But she or he may have forgotten to read the group's guidelines.? Files should be uploaded into the

Who?

So.. what? bandwidth are You looking for?

Thank you for your reply and the test file, Andy. Indeed, splitting v(out) into v(out)@1 and v(out)@2 clearly revealed the missing part at the end, and so the crazy fft plot makes perfect sense.

"In that case I would suggest capturing waveforms on a transistor driving a dummy load, and matching them by modifying Rb for a model that is known to already have correct high-frequency behavior. One

It’s a somewhat obscure figure of merit in statistical analysis. An R^2 of 1.00 is as near perfect fit as possible, of a formula to a set of data. Anything close to that, is “close enough!” Dave

Hi Jerry, I am investigating a NMOSFET based class E oscillator. The BJT will be used as a driver for the mosfet and part of the feedback loop will include the rbb and the cap_be of the BJT in series

Thank you keantoken. I am interested in the Rbb at high current values. Would the s-parameters help for this estimation? If if does, then please provide some guidelines on how to do so. I am already

IIRC, we've been told that v24.1.3? restores LTspice's ability to generate the netlist, but the netlist it generates is no longer usable as the input to new simulations Stupid.? Er, Bummer.? No, it

Do you want to experiment with this in relation with noise voltage? You could probably build a theoretical model circuit of your transistor and adjust an explicit Rbb' until you have coincidence
