    Dimmer Circuit Simulation Problem

    Hi I am trying to make a dimmer circuit with proteus. But it is not working according to our calculations. I am very new both in proteus and also learning about OP-AMPs. So I am not understanding what's wrong with the schematics. Both the current and voltage is showing zero. Here is the...

    LTSpice - what programming language does it use and how do directives hang together?

    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...

    LTspice ECG

    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.

    How do you load a PSpice netlist into LTSpice and run an analysis/generate a schematic?

    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...

    How to import a third-party SPICE model in LTSpice that doesn't have a generic component!?

    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...

    Simulate PSoC in Proteus

    Hello. I am working on extracting strain gauge values mounted on my ATV (front suspension) with the help of a 20 bit ADC of PSoC. Before that I would like to simulate it. So could you please suggest how can I do this in proteus(or any other SW if not possible). Please help. Thank you for your time.

    How do I EM-Extract a subcircuit and define a different em/drawing-layer than the original circuit in AWR?

    I have a 4-layer project in AWR/MWOffice and have built a parameterized microstrip inductor schematic (named "spiral") with a "Line Type" of layer1 that I wish to reuse on another schematic as a subcircuit (SUBCKT) on layers 1,2,4. When I place "spiral" as a subcircuit on another schematic...

    How do I simulate these two different Line Impedance Stabilization Network (LISN) models in LTspice?

    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...

    LT Spice help

    Dear guys, I was wondering about a problem in my designed capacitive sensor, why the simulation is not executed as wished. When I simulate the output difference between Vout1 and Vout2 without connection to the Schmitt trigger it looks like really well, but when I connect it to the Schmitt...
