ltspice

Hi everyone, I was simulating a simple RC circuit to find it's frequency response using the following two third party Murata capacitor models GRM155C71H104JE19 and GRM155C71H103JE19 in the following circuit. I received the following error message: Multiple instances of "C1"...

Hi, I am trying to plot frequency response of 741 op-amp by LTSpice. No matter I tried, I can't get the plot to be shown. I am a newbie as I just started with LTSpice yesterday. I have attached the file below, please help me to inspect what did I do wrong. Thank you so much.

Viewed 1 time 0 The subject is to make ro=500k, ID=100u by setting VG3,VG4 and W/L of MOSFET. And I got the exact values from Hand-calculation, and am trying to test it by using LTSpice. I did make this schematic. and DC currents of two mosfet was around 74uA (I don't know it is right way to...

Hi, There was an example from my book and I wanted to build the same circuit on LTspice to test the results. However, when I create to simulate the circuit in the LTSpice environment you see below with the different outcome values. and here my ltspice results: I could not find the same voltage...

Hello! I'm using LTspice and I'm not quite sure how I'm supposed to do the dependent source as it isn't dependent on a component. The circuit reference and my attempt (which turned out wrong) are attached below: Thanks in advance :)

Dear all, I am trying to simulate my synchronous buck converter and I managed to implement complementary signals to driver two different transistor. The issue is as follows: 1- I inserted dead-time (green circle) but the problem is that at the start of the period two signals overlap...

Hello all. I am conducting a simulation based report on resonant inductive coupling. I intend to calculate power transferred as a function of input frequency. For this I used the formulae for self resonant frequency and calculated a SRF of 3.283MHz using 10mH, 235pF and 0.25Ohms as my values...

1. So Vim has vimscript, Emacs uses Lisp - what is LTSpice doing? 2. You can use .step to update a {R} for .meas and calculate MAX/MIN etc - how is the data being passed and how do the various directives influence each other? Note in the schematic, he uses {R} and 'r' and R1 and they are all...

I am simulating the triac control on example circuit. Alhtough the simulation run sucesfully, I got: in the SPICE Error log at the begging of the simmulation. Do not know where is the line 18 mentioned in the error mesage.I don't know too, how to enable the sweep resistor legend to display...

Hello. I am trying to create, for a project, a 2:1 Multiplexer using CMOS Transmission gates. This MUX requires 2 transmission gates, so 4 total transistors. I have seen some implementations use an inverter when connecting the Select bus. I am pretty bad at electronics. Take a look at my...

Hello! A little about me , i haven't formally studied electronics, i do not own or have access to an oscilloscope. I have been researching about MOSFETs to use an IRLZ44N as a switch in a basic boost converter, on the IRLZ44N datasheet Vgs(th) = 1v to 2v, as i undertand this Vgs(th) is the V...

Hello. Thank you for clicking on my article. I'm from Korea and a college student. I'd like to find a solution. My circuit simulation speed is too slow. So I want to speed up. I saw what other people did at Google and made it. I want to speed up the simulation. I'd appreciate your help.

Hello all, New to the forum and came here to get some more information about simulating mains voltage Triac circuits. My issue is the following; I have an opto-isolated TRIAC control circuit for a resistive load (water boiler). I know that Triacs generally have a junction voltage drop of ~1-3V...

So I have this simple resistor divider circuit in PSpice/from a book/NGSpice - how do I load it in LTSpice/Linux/Wine? (I'm reading from SPICE A Guide to Circuit Simulation but I am also reading from Passive Circuit Analysis with LTSpice. The former has the example) I tried manual loading in...

Hello all, I don't know if i am supposed to ask this kinda questions in this thread but i am going to anyway! Tried importing a spice model for BAV70 (Dual-diode SOT23 package) after seeing some tutorials, all of them use a a generic component that represents the symbol of the SPICE model...

Hi, I was hoping someone can help me to solve my error on LTspice. I am designing a three phase voltage sensor using voltage divider resitors and a isolated differential amplifier. The voltage range I need to measure is max 440V_rms. I want to add protection by adding a thermistor and MOVs. I...

Hi, In LTspice, I have a voltage. I want to convert it to a PWM. This is only for LTspice - it doesn't have to be a something that can be realised. Tperiod is 10ms. So if the measured voltage is 2.3V, and my reference is 3.3V, then I want a PWM to have a duty of 69% (2.3V/3.3V). So Ton 6.9ms...

Hi, I made a circuit that charge Li-ion battery. When I simulated it, I found something strange; the time for charging was too short. I made it with 'LTspiceXVII' and here's my circuit's diagram and the graph, also I uploaded the 'Li-ion bat file'. So, would you like to help me if you don't...

So, I found these models for Line Impedance Stabilization Network (LISN) in two different books. I want to simulate these two models in LTspice, but I don't know which side to connect the EUT and which side to connect the spectrum analyzer and ofcourse, where to connect the source? and how do I...

Standard.dio (diode models) (https://forum.allaboutcircuits.com/attachments/standard-txt.65504/) This is an updated version of the diode models file, which includes the 1N4001 diode, which is what i'm after. I replaced the file in /cmp with this one, but the program doesn't list any new diode...
