ltspice

Hello there, I've been try to learn how sigma-delta ADC works, I've been through the block diagram mostly and tried simulating one myself by following this video lecture from "The signal path" channel, the wiring is right as it shows in the circuit diagram( from timeframe 34:30 ) and it also...

Hello, I'm new to ltspice. How can I add a varistor to the memristor moderation so that the current-voltage characteristic is nonlinear? I am attaching the files.

Getting "could not open file.." shown in the first image, when trying to do transient analysis, is my circuit wrong or am i missing something

beginner here, i imported a spice file into ltspice but in the datasheet it says its 8 pins but in ltspice its 5 pin, did i do something wrong or am i missing something

Hi I want to simulate this IR2103 based half bridge circuit but LT spice seems to be throwing an error: "Analysis: Time step too small; initial timepoint: trouble with node "u1:_gd_template:_input_stage:_lin_th:outp"" I got the spice model for the IR2103 from...

Hello! I'm looking to the state variable filter proposed from ESP in Project 153 that is a state variable filter that splits the signal in 3 bands and sums them back together. this should give a flat response all over the spectrum when the bands are summed back together. I simulated the circuit...

So, recently i have been trying to import IR2110 driver IC for simulation, i found this PSPICE model from the infineon website, i did the following steps, i) open the .lib file of the component in LTspice ii) click on .SUBCKT and "create symbol" option but when i get all the connections right, i...

I'm trying to build a simple PWM modulator to convert the analog Audio signal into an PWM waveform, the triangle wave generator works fine and i have used an AC sine wave as an audio input, with an DC offset to match with the Triangle wave reference, but couldn't get the comparator circuit into...

I drew this circuit in LTSpice. I want to find DNL (Differential Non linearity), INL (integral non linearity) and THD ( Total Harmonic Distortion ) of the circuit. Please Help me. Its very urgent!!

Hi everyone. I'm struggling with LTSpice and the use of external components downloaded from TI or AD... I have the same problem as the guy in this post: https://forum.allaboutcircuits.com/threads/import-lm358-model-into-ltspice-xvii.160321/ But there is not such a ".cir" file, just the ones...

Hello everyone, I'm new to using LTspice, I need your help in modeling the behavior of the following memristor.Сode taken from the attached article

Hi everybody, I'm a beginner with LTspice, so I'm sorry if my question is related to some basic knowledge that I don't know..any help is really appreciate!! I can't solve a problem with my circuit in LTspice: I have this error "singular matrix check node vout+" and I don't know what to do. I...

First of all I would like to say that I am very newbie in this electronic design. So please don't get upset if this question is too stupid. I am designing a circuit with opamps that can provide +3V and -3V and that can deliver 0.5 Amps. I know I can use the Lm317 and Lm337 but this time I would...

I'm dealing with a problem finding a solution to output ripples. How can I reduce this output ripples using imperfect capacitors and imperfect inductors ? I've tried using 330u Tantalum capacitor but it was imperfect so the series induction made it look like in the picture. I also have...

Hello ! I've got a problem with simulating converters in LTSpice. When I simulate 3 of my converters in one file their result is completelly different comparing with individual simulation : Here is an example where input is 7V and the output is 3V with I_max = 350mA. The left side is...

Hello guys! I'm using LT8705 to make a battery charger to charge my 6s NCM battery pack. But It seems that the LT8705 don't have the reverse current protection and will start in CV mode and then into CC mode thus presenting a high current before getting into CC mode. So I'm trying to use LT4364...

I'm copying “Ultra-Wide Input Range Non-Isolated 12V Buck Converter” from LT8316 datasheet into LTspice. But the results seems to be very strange. The voltage on FB is even higher than Vin, which is way above the standard reference voltage(1.22V). I can't find any difference between the...

I am trying to simulate solar cells of a solar module with 72 cells and see the effects of partial shading as well as the activation of bypass diode. For now I am just simulating 2 cells of the PV module. I am confident that the model works without the bypass diodes, when I plot I(V1) vs...

Hi I am doing a double pulse test of MOSFET (PN: IAUS300N08S5N012TATMA1). Since we have high voltage spikes and oscillation of Vds in hardware testing, I am also working on LTSpice of double pulse test. I am so confused about the parasitic parameter of the MOSFET lib, I know the MOSFET has...

Hi, I want to have a clean switch on my schematics, without the voltage source that controls it. That I will put it on a side... I tried to modify the classical switch and pass the nodes for the voltage source that controls it, as parameters, but it does'n work... Do you have an idea how to do...
