I got this model for a mosfet, FDB390N15A https://www.dropbox.com/scl/fi/ko6yvs1jo1j4svunwrmtc/FDB390N15A.lib?rlkey=o012wl2xqh3vjyoz7i7vbx 59t&dl=0 And want to run it in LT Spice. I named my mosfet FDB390N15A and I did .lib FDB390N15A.lib and .inc and .mod too but it complains that it "can't find the definition of model FDB390N15A". I never really understood how to conn

I have updated my MCP6001 Spice model to include better swing control and added an output stage that reflects load currents into positive and negative rails. It can be found at MCP6001_JT.zip on the Device Models & Subcircuits page of my website. Please try it out and report any problems via the E-mail Icon on the Home page of my website. Thanks! ...

I'm wanting to simulate noise in a TIA. It will use a discrete jfet at the input, then opamps. Check me out on this, please: I assume the jfet models have built-in gate equivalent noise voltages and currents, somewhere in the model string. Also assume the the LTC opamp models include noise params. Ditto Johnson noise in all resistors. The LT Spice help pdf file says that.....

PING: Aylward or other Spice Expert... Bringing up a 0.18u/0.35u Vanguard process, building up the PSpice model libraries. Discovered strangeness: ALL devices have HDIF=0.2u, except "native" NMOS, which has HDIF=0.02u!! I thought this might simply be a typo, but that HDIF value is repeated in each of the corner parameter statements. 0.02u seems awfully small to me. Can this be...

Following the exchanges on SEB, about autotransformers, and turns ratio, I wrote these models. The subckts should run on any SPICE which supports .param and rser/rpar. The .asy files are for LTspice. The symbols should pick up the subckts without any need for a .lib directive. The first is simpler, requiring primary inductance, turns ratio, and primary resistance. The second examp...

Could some electronics guru tell me what is the maximum signal frequency that the SPICE can handle ? I have experimented with a simple low pass LC filter and found that the maximum input frequency that it can handle (before the output looks like junk) is 1 THz (10^12 Hz) even when the cutoff has been set to 150 THz. What are your experiences with this ?

I am experimenting with SPICE microstrip dipole antenna models. The series RLC lumped element model is assumed. For a half-wavelength microstrip dipole antenna, the inductance value of the two microstrip segments is computed using values for trace width, thickness, substrate thickness and effective dielectric constant. The capacitor value is obtained by using resonant frequency

Could some electronics guru here please clarify this a bit ? I am experimenting with SPICE transient analysis of oscillator, and I am unsure as to what to set as the ideal sampling time, given that most oscillators will generate a fundamental and a few harmonics. For example, suppose that I have a 500 MHz differential oscillator, and I set the sampling time as 1/(15.0*time period of fund...

Could some electronics suru here clarify this a bit ? A planar inductor has a frequency dependent resistance(skin, proximity effecrs). Can the small signal S parameters for such an inductor be measured using stabdard SPICE small signal(.AC) analysis ? At each frequency in a specified frequency range, the series resistance is different. Does this new resistance at each frequency have effect on ...
