Re: Running TI Models in LTSpice
You can run them if they're defined with, e.g., PSpice subcircuits. Latter versions of LTspice comes with documenation about making symbols for 3rd party devices. --Mike --- "polapart

Re: Noise source in Transient analysis #NOISE
You might be able to use the rand() function to get what you're looking for. Check the example ./LTC/SwCADIII/examples/Educational/PLL.asc There it is used to generate a random bit stream by boolean

Running TI Models in LTSpice
Is there a simple way to convert TI models to run in LTSpice?

Noise source in Transient analysis #NOISE
Hi everbody, does anyone know, how I can add a noise source in a transient simulation (if it is possible at all)? I tried to modell a noise source with a behavioral voltage source but i didn't work.

Michel, I think this as a problem in the definition of the lossy T-line symbol. Try updating to 2.00c and possibly redrafting the schematic. Congratuations. Yes, this is an aspect of the help

I experienced the following problem using a lossy transmission line. Even though the simulation (.op) can proceed, a non fatal error is occuring all the time: Unknown parameter "td". As I read in the

Re: Version 2.00 is now available
Version 2.00 of LTspice/SwitcherCAD III is now available. From Version 1.16s, this version introduces 1. a graphical symbol editor 2. hierarchical schematics 3. improved help documentation. The

Re: Converting PSpice MOSFET models
The line "SYMATTR Prefix MP" should read "SYMATTR Prefix X" in order for the symbol to be used with a subcircuit definition. See Helmult's notes on the subject. --Mike --- "Dale

Re: .backanno
Ralph, .backanno directs LTspice to embed port information in the .raw file so that the waveform viewer can refer to subcircuit port currents by pin name. The command is placed in every netlist

Hi, Pardon my ignorance as I am a Ham running small spice circuits, but I cant find any documentation on what the dot command, .backanno, means. I would appreciate a pointer to the documentation for

PS: Re: Converting PSpice MOSFET models
PS: It's rumored that most of what the subcircuit models attempt to do can be done by specifying parameters in the higher-level MOS models (the "LEVEL=__" parameter) but I haven't found any

Converting PSpice MOSFET models
