Hi there!
I am currently looking for 2SA1708 and 2SC4488 transistor models to integrate into Spice, but I could not find any model on the web. Could you please help me if you have the related models? Or can you please give me feedback about what parameters are the most important ones to model...
I am trying to simulate ADA2200 in Multisim. The device is not readily available in Multisim library. So, I downloaded the SPICE netlist code for it from Analog Devices. I tried to make a component in Multisim using this code. But I am encountering an error (It was also commented in the code...
There is the code
’npn transistor
vbias 3 0 dc 5v
vs 1 0 dc 0v
rb 1 2 20k
rc 3 4 2k
q 4 2 0 mynpn
.model mynpn npn (BF=175 IS=1e-17 VA=75 BR=2)
.dc vs 0 5 0.5
.plot dc v(3) -i(vbias)
.end ’
But the output is showing a negative going down. How to get the graph of the plot with this app called...
The thing is, I am confused with rawfile and .print card (spice.out file).
There are like 3 options for rawfile generation: NONE,COMPACT and ACCURATE. While I am using NONE with the .print card the result is going inside a .out file without generating a rawfile. But when I am using ACCURATE or...
The code is here,
Diode Voltage Drop
r1 1 2 10k
r2 2 3 5k
r3 3 4 4k
r4 4 0 3k
vin 1 0 dc 10
.print dc v(3,2)
.end
As you can see I am trying to get a voltage drop between node 3 aand 2. But the print function is not working properly. It is just showing the usual outputs of( the ouput is...
Once i build the inverter circuit and simulate using SPICE tool, i can plot the I-V characteristic...Is there any possibility to change the built in drain current expression..[for eg :instead of Id= 0.5K(vgs-vth)^2 to Id=0.5K(vgs-vth)^3] ?
I have a project, first i need to find a circuit to Analyse/study the Frequency Response of Heterojunction Bipolar Transistor. Then simulate that circuit on SPICE (i'am using Orcad Cadence).
Can someone help me finding a circuit as mentioned above???, I'm having difficulties finding one. Any...
