Dear all,
I used LTspice SW few weeks ago.After completed a JFET Amp. polted the AC analysis the result is fine but I want to check the Amp. distortion,I can't find this function at LTspice.Does any one tell me how to do this function at LTspice or other simulation SW can do that ?
I read the LTspice manual carefully how to check the noise function at LTspice but I can not understand how to do,does any one help me ? Enclose are the circuitry and AC anlysis ploting result for your reference.

Best regards,
Gilman Li.

Join the LTSpice group on YAHOO. Look in their FILES section for examples on how to use the .DISTO function, Spectral analysis, and .NOISE analysis.

while designing op-amp in LT spice, the output some times is in KV rating i don't understand from where KV come as i apply less than 10v so, how it is possible.

pls tell...!

You are doing something non-physical. e.g. feeding a current-source into a very high-impedance will produce kV. Post your circuit.
