Well, suppose you have a gain 2 non-inverting setup. Vin+ > Vdd/2 means the op-amp cannot actually make the summing node Vin- anything like Vin+. So Vdd=5, Vin+=5, Vin- = B.rail = 2.5: error is +2.5 -

I need Li-ion battery model that can be simulated in lt-spice (4.2v) rather than charging ckt...If any1 had it..plz post it to me Thanking u

I really have to bite my tongue here over Carl's poor aim at uploading files. LTspice should be able to reproduce the transitory MOSFET oscillation just fine as long as the circuit model is reasonably

Hi Tim, Thanks for the zip, but I can't find symbols "Potentiometer2". Richard

This is the problem 1. Maximise LTSpice 2. Maximise the schematic 3. You run it, add cursors. 4. Swap back to tab: It's a pain to have to close the dialog - and moving it won't always help, as you'l

The cursor dialog shown on plots lives on top of the schematic too: even in "full-screen" mode (not tiled, not cascaded). Surely it is not a good thing that the cursor dialog is visible when I change

It can be a real chore to make something oscillate when it doesn't want to. You mentioned a long trace. Does your schematic include wires or traces? I mean REAL wires? SPICE nets are ideal: zero

Thank you Tony & Helmut I'll try the 'rail' method initially Regards Stephen.

Hi John, Would that actually help with my overdrive (saturation) recovery issue? That is, I'd like to be sure the op-amp itself never hits the rails. I don't yet see a way (in or out of loop) to add a

That sounds like you have a trace on your circuit that is acting as what used to be known as a Lecher line, but these days would be classed as a transmission line stub.

Hello? Does anyone know where I can get a model for the H11L1 optocoupler? ?There where some messages about this part a few years ago (2011), and it appears that someone came up with a model and

I have a PC board with a FET that has a high-frequency oscillation because of my sloppy layout. I'm trying to simulate the oscillation effect, but I'm unable to make my simulated circuit oscillate! I

Does anyone know where I can find a model for the H11L1 optocoupler?

Hello, Has anyone ever built a model the adjust the Rdson of a MOSFET whilst running so that you can change the coef as the temperature increases, i.e. with use of RC thermal models? Cheers Waynel

Lohith, It just happens that I have been using this same charger on a project and created a simulation for it that contains a Saft battery model that is fairly representative. Maybe it will be useful.
