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.

I have been working on LT3652 for solar panels for which I need a li-ion battery model inorder to simulate. Can u suggest me some links or models?

Hello Dave, You missed the parameter FIREANGLE. I have added it. I also reduced the number of curly braces. Please use curly braces only around the whole expression. PULSE(0 10

Hi team, I've a simulation?of a three phase voltage converter with resistive/inductive load. The switching devices are back to back SCRs. I wish to control the firing angle for the SCRs based on the

Hello, You can change the parameters of the UniversalOpamp2 when you right-mouse-click on it. There you will find the parameter "rail". This parameter specifies the minimum of |Vsupply-Vout|. Example

Sorry for the late response - catching up after return from vacation. I've successfully simulated numerous p-p valve (tube) amp circuits using the simple model posted by the OP, albeit with higher

The UniversalOpamp2 has a reasonable method of output limiting already builtin. The parameter "rail", which is set to 0, by default, is the "closeness" the output is able to approach the rail. If you

The internal representation of the level.2 op-amp ("UniversalOpamps2.sub" ?) does not seem to use actual transistors, presumably for speed of simulation and to make it more generic. What external

oops.. Sorry, I meant the "Equivalent Schematic Diagram", Figure 51. on the datasheet, not figure 2. HT

Hi Andy, "I am not so sure about that. Doing that would make the resistor between pins 11 and 12 unnecessary because it would be shorted out. I think they meant pin 12 to not be grounded in the Tach

Mike, Helmut is exactly right, but it is really energy that is transferred between the inductor and capacitor. The inductor current becomes charge on the capacitor and the charge on the capacitor

Hello Mike, Initial current in an inductor has the same meaning as initial voltage in a capacitor. You can think of it as a "charged" inductor like applied voltage to a capacitor which is a charged

Andy, I can't figure out how to quote your text with right brackets to separate it from my reply. Thank you very much for the detailed reply. One thing I didn't think of was to pick up the part and
