I'm only using LTSpice at hobby level. I've created a component for bi-di current-sense amplifier INA181 from PSpice model supplied by TI and a little test schematic

Do you mean the effect of tolerances on component values? It doesn't have anything built-in to do that, but there are several ways to do it, ranging from a simple. STEP to nested .STEP, and some other

do LTspice have .Sens analysis (can perform the sensitivity analysis)?

UPDATE: I read that i should use 100Mega Ohm resitor to solve my ltspice problem. i did referenced the Vdd as you said. Is it possible? to make the circuit at #153738 work in LTSPICE so the output

Hello Andy, Exactly I have referenced the output VDD to the VSS so VDD=VSS+8 as shown in the attached LTSpice circuit and models below.However as you can see in the attached photo ,The output is not

Oops.? I wrote that using Rser=1n for the upper two inductors fixes the math errors (-1.#IND, 1.#QNAN) for the K=1 case.? But I was mistaken.? Sorry. Andy

Elien, Please stop uploading your .RAW and .LOG files.? Those should not be uploaded to this group.? Please take a minute and re-read the instructions on the group's main website (

Hi, I was curious what VCO model is used by SIMetrix. I did some translation of the model to LTSpice. There are strange solutions, negative references, etc. ... The file is here:

Andy, Thanks for your suggestions. I uploaded a modified version of my schematic, "IPT_LM_modified.zip" in which I have solved the syntax error. When I rerun the simulation, I encounter a "singular

Hello Andy, Thanks for your replay. I am playing around PLL average models, comparing results with time models. Using MODULATE won't give AC response but using BV with V=

bb_petrov, This error message happens because the original code you used has an A-element (one whose name begins with an A) that is unique to another SPICE program, and doesn't work in LTspice.? In

I don't know if this was answered.? Bernt wrote, " However, what I do not understand is how to then place my symbols. In the Place component, it only shows stuff from the .lib (which includes

Elien, It is also worth noting - In your circuit, where you have a resistor in series with your inductors L1-LM and L2-LM, you *can* move the resistors into the inductors by setting Rser = 1.3 ohms on

Elien, Unrelated to your question - Be aware of these things, which might affect your simulation's apparent accuracy: * Non-coupled inductors in LTspice have a default series resistance of 1 m = 0.001

When you define k<1, you don't need to define the mutual inductance, nor the leakage inductances. LTspice does it automatically.

Elien wrote about an error "Missing inductance value".? There were several other errors too. Elien, the reason is simple, but might not be obvious.? You used parameters named L1 and L2, but you
