Dear subscribers of the LTSpice-List, I uploaded the concerned Schematic and the model of AD734 to http://tech.groups.yahoo.com/group/LTspice/files/%20Temp/AD734%204-Quadrants-Multiplier%20/

There is no inherent "time step" in LTspice. If you are thinking of a discrete-time system, then you need to add a "clock" (a pulse at some convenient frequency would work), and a sample/hold circuit.

Thank you for the options suggested.Could you give an idea how to implement 1 sec delay using B-element.

There's nothing wrong with the model, as such, but there seems to be a couple of issues with the circuit that you're simulating. If you overcompensate it, you'll get a better idea about what is going

Hello, have not posted here for quite a while! I have a number of schematic files that have a small lock icon just to the left of them when I display the files in a folder. When I select all the files

Andy, Nonlinear inductor work fine in the frequency domain. The first thing LTspice does for an .AC analysis is to find the DC operating point. Then any nonlinear devices are linearized at their

Hello Steve, You could name the opamps U4A, U4B, U4C, U4D and do some extra post-processing to modify the PCB-netlist. Maybe this earlier discussion will help. "pcb layout s/w for use with ltspice" It

Forgive me for asking such a basic question but is it possible to link several symbols (e.g. *.asy files) to the same package? I mean, say I have a quad opamp. I would like to position each of the 4

Hi Andy, as the game plays in the RF ham area, the AC view will be the right way ! I will try to find out, how it will work with the a table . Thanks Herbert Am 14.07.2013 18:08, schrieb Andy:

Hi Alzie and aall the others which answered, Alzie is nearly right with the way of explanation what I have seen, but it is not possible to describe the behaviour by S?ICE just with a parallel

Are you talking about GNU Octave and are you working under windows or linux? If you are working under linux then you may be able to write a netlist for ngspice. You would then be able to run all

Dear Andy and Dear Fred Firstly, I really cannot explain my feelings when I see that you do your best for to solve my problem, I thank you very much. Couple of days ago, I was in vacation and I was

No, it would not. The first thing LTspice does is find the initial operating point. Voltage sources are set to their DC values, and effectively LTspice "waits" until everything stabilizes, before

Look at the .tran card (it's on the schematic.) Right click it and look near the bottom of the dialog box to find "skip initial operating point solution" and check it so that this step will be

I am looking at simple RC circuit with a time constant of 1 sec and a 6 V battery. Doing a transient analysis, at t=0 the capacitor is already fully charged at 6.0 volts! I don't recall giving initial
