Thank you, Tony - that's even better than what I was looking / hoping for. I'll be studying what you've done to become more adept at it. I wasn't even aware of the measurement subsystem before, and I

Hello Donald, Thanks for the pointer. Does this imply that I can turn a suitable enhancement mode N-chan VDMOS into a depletion mode device by just inverting VTO? Sounds so easy ;-) ! Jan Didden

Oooops - just found a problem with using .PARAM statements to do what I wanted. To briefly summarize my objective, it is to plot a trace of the energy stored in a capacitor over time. I want to use

Hello Alan, I just tried again with gshunt to check that it really has been used inside the subcircuit. I got +25% more supply current even with only gshunt=1e-11. The more interesting option is gmin

Thanks guys, I thought this only add to the external circuits, not the inside of the opamp. Now I know. I notice the Ti models don't work as well as the LT models, The LT models don't need to play

Thanks so much Andy, and the other folks who responded. That's the approach I'll use. To answer a question in one of the responses about what I'm trying to do, it's to try various values of C, L and

Ala, Gshunt should probably be no larger than 1e-10. Your value (1.5e-7) is a thousand to a million times too large. Side-effects like the ones you observed should be expected. Andy

Richard, TRTOL is not very well understood, by most of us. Almost all SPICE programs set TRTOL to 7, which is a slightly odd number. Most SPICE users don't change that. LTspice's default is 1, and

Thanks to all who replied to my question about this. Larry Benko

Hello, Adding 6MegOhm resistors from every node to GND will kill practically every circuit, because there are resistors with kOhm to MegOhms inside the subcircuit. Best regards, Helmut

Hi I encountered a strange problem, I uploaded the file in Temp. It's a simple circuit using LT6202. If I put in .option gshunt=1.5e-7, you can check current through R2 and R3 is 50mA. But if you

Ok. Sorry. I've solved the curiosity. I put in a delay in my gate drive to allow for the delayed "startup" voltage sources. It was my delay causing it to wait 20us before doing anything..

Thank you both Bordodynov and Andy. That was extremely helpful. I'm hoping you can confirm my understanding, that reducing TRTOL slows the simulation but should make it more accurate. It should not

I remember I noticed this but also that there was an entry in the changelog about this and, sure enough, here it is: 04/24/18 Corrected the behavior of SINE voltage and current sources when Ncycles is

Hello analogspiceman, Thanks for your uploaded example "sampled_average_expanded.asc". I have now a better understanding after I plotted V(4), V(3) , V(x) and V(s) in one plot.
