Ameur

Hello everyone, I would like to change the background of the plot from black to white but I don't know how, does anyone know how to do that ? I'm on NGSpice. Thank you

Hello, I'm trying to simutale the charging of a capacitor with a transient but I couldn't see a charging curve. It's already in the beginng charged. I don't understand, does anyone know why ? Here bellow my code RC charging V n1 0 1.3 R n1 n2 10k C n2 0 5uF .tran 0 20ms 0.01ms .control run plot n2 .endc .end Thank you :)

Yes I copied it and pasted it and it still doesn't work, it's maybe because of ngspice. "No. of Data Rows : 637 Error: plot: no such variable. i(vs): no such command available in ngspice Doing analysis at TEMP = 400.000000 and TNOM = 27.000000 No. of Data Rows : 637 Error: no such function as dc2.i."

Yes I copied it and pasted it and it still doesn't work, it's maybe because of ngspice. "Error: no such function as dc2.i."

It didn't work (i'm on ngspice) "Error no such vector as dc1 and dc2"

Hello I'm trying to simulate the characteristic curve of an NMOS for different temperature but I didn't manage to plot each analysis for each temperature on the same grahic. Can anyone help me ? Here the code Ameur M d g s b m1 L=0.6u W=10.0u vgs g 0 3.5 vds d 0 3.5 vs s 0 dc 0 vb b 0 dc 0 .model m1 nmos ( version=4.7 level=54 lmin=0.1u lmax=20u wmin=10u wmax=100u ) .dc vds 0 4.5 0.05 vgs 0.5 3.5 0.5 .dc temp 25 50 5 .dc vgs 0 3.5 0.1 .control run plot i(vs) ylabel 'Caractéristique' plot i(vs) ylabel...
