Title: simulation of circuit
Post by: ishakderbak on December 09, 2024, 01:10:16 pm

i need to simulate filters circuit
 this is for my reportlab
I would be glad if anyone could share simulation circuits with me since I struggle with them

About the simplest  and free simulation software out there https://www.falstad.com/afilter/circuitjs.html?startCircuit=filt-hipass.txt (https://www.falstad.com/afilter/circuitjs.html?startCircuit=filt-hipass.txt)

what i will put in Ve and Vs

You have to drive Ve with AC voltage source and measure Vs (amplitude/phase). Spice should give you that.
I can't be more specific. From Spices I used only PSPICE that I got demo at CEBIT messe around 1995 and used it last time about 15 years ago (since I moved from Windows 32 bit to Windows 64 bit it refuses to work). In 2023 I spend 2 days to check how Spice integrated in KiCad works.

LTSPICE

Its free and everyone uses its coz its good

No Brainer & no idea why its not already been recommended . Never heard of the other stuff mentioned?

Never heard of the other stuff mentioned?

About 2005, after 10 years of using PSpice demo version (limited to 30 nets, but it was even too much for my needs) when I practically simulated all what I needed I got info about LTSpice. I tried it, but
I was lost in the fact that I had to write out some text commands in the schematic instead of setting the voltage/current source parameters after clicking on the source symbol and simply setting the simulation parameters in the dialog box opened from menu like I had it 'since always' in PSPICE. In the dialog box you see what you are setting while writing command you have to remember all symbols to be used.
Do in LTSpice you still have to write text commands at schematic?

I practically don't need Spice, but as KiCad (that I use to design PCB) have Spice in it (not very flexible yet, but each year better) than why not to have two tools with one schematic drawing interface...

Just use LTSpice.
