Hello, I have uploaded an example with a time-variable resistance. R=1k+5k*(V(ctrl)+1) Files > Temp > ni-opamp_.asc Best regards, Helmut

Hi, In an inverting amplifier(Uploaded File: http://groups.yahoo.com/group/LTspice/files/%20Temp/ni-opamp.asc), suppose R2 fluctuates very rapidly (say at 10KHz or even higher, may be due to some

Hello Tom, You could plot the results from .MEASURE View -> SPICE -> Error log Right-mouse-click -> Plot Stepped data You could also copy the results(numbers) from the Error Log file to any math- or

Greetings. How can I find the max or min of a .measure command from a Monte Carlo run? my command --> .measure dc trans find I4 when V(N016,N002)=0 Question: how to find the max or min of the data?

I don't see either of these in the standard library. I placed a pnp in a new schematic then right-click Pick New Transistor. I just did a sync release too. Decades ago 2N2955 was a silicon part

This is a homework assignment, right? Let me ask you this: Did you go to college to learn how to do those things yourself, so that you can become a good engineer, or are you looking for free handouts

SPICE models for INA193 and AD8210 are available in the web site of TI and Analog Device respectively. Regards. Varoli -- Prof. Vincenzo Varoli Politecnico di Milano Dip. Energia Via G. Ponzio 34/3

Hello, is there anywhere a model for a bridge current sensor available for downloading? Thanks Mario

How to use .param and .tran simulation in LtSpice? Please show its use in this question- Use SPICE to plot the output characteristic for NMOS transistors with different Length's (constant W/L). For

What Andy said. What editor you use to generate PWL files with is the whole ball of wax, beyond just the more obvious PWL entry errors. Even the manner/format of the saved file, aside from the editor

We can't read your mind so we can't fix the problem if you don't show us the data that causes the problem. But speaking generically ... PWL data must have an even number of values. The error message

it would help a lot if you uploaded your circuit to the website. Attachments do NOT work on yahoo.

Dear All I am trying to use a PWL file in a current (I) source however an error pops up every time saying "Missing value for final PWL time in source I1". I've examined my data file many times and no

Thank you very much aurora_iii it's all clear to me now. Another input from a friend re. using the Hierarchy to create symbols and the realisation that one can open one's own directory in the

Both file names still say PNP. Does someone know how to rename the AC127 file to NPN?

It all depends on the font your email program uses. You probably drew it in ASCII for a fixed font. Schematic symbols in LTspice are easily modified. LTspice includes the symbol editor. Draw it the

I don't know much about the details ... but EG=1.3 might be a bit high for a Schottky diode. The LTspice help docs imply a value of 0.69 would be more typical for a Schottky. But I would be very

Hello, You could change the parameter Eg and then rerun a temperature simulation while watching the forward voltage. You should get something like -1.5mV/°C to -2mV/°C. Best regards, Helmut
