I have received an example schematic of how an audio preamplifier should look like. Based on that and a set of data(input voltage(7V), input resistance(60 ohms), output resistance(8 ohms) and amplification(2.1) ) I have to design my own schematic(which shouldn't be a lot different at the end of...
Hello Friends!
I have generated a similation of 2x4 decoder.
Everything was fine but I don't know how to read the output of [0:3] d. Means I don't know how to read the output of the decoder. It seems it is changing the voltage while I am changing the input. But I don't know how to read the...
I recently started to use NGSPICE.
I can make simulations from code. But it would be great if I could use something that can give me a schematic design. I am using a linux distro on android(using userland). So I can't use any heavy applications. How can I get schematic from .cir or .ckt file easily?
Good afternoon,
As the thread title suggests, I am having trouble simulating the UC3846 model in LTSPICE. I have gone through the process of creating the chip and adding it to the simulation space, but when configured in a similar way to the "Typical Application Diagram" from the data sheet it...
Hello :happy:,
I have in the recent days tried to simulate the temperatures levels in a charger (AC/DC-module) in a Heatsinkcalculator software:
**broken link removed**
Based on the power losses calculations for half-bridge, where we have two MOSFETs that are operating one at the time,
where...
Good afternoon to everyone. I am researching about electrical protections in the industry and I was wondering if anyone knows any program to simulate the defects that affect electrical systems. Thanks in advance
Hello,
I trying to find a equivalent battery model for a PHEV (plug-in-electric vehicle)
and simulate the charing process in LTspice.
I want the battery to have SOC=0, an empty battery from the begining, and starts to charge between the charging range of 320-380 V. I know the battery should...
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...
hello guys, I am new to this forum . I am implementing md5 in Verilog. I am almost done with it somehow but still stuck half in a way.. can someone can help me in finding the bug in the rtl. I have referred pancham md5 source code for it and have modified a little bit as per my application...
Hi All,
Recently wrote this little script for Octave/Matlab and thought I'd share it here in case it is of any use. I had a look to see if there was a native way to extract the data I wanted (or if someone had already writen a post-processor) but couldn't find anything. If another (better) way...
Hi everyone!
Im wondering if someone can help me with something. Namely, i should make a project depicting a simulation of 6 members voting for a choice (one of them is the president and his vote counts as two if voting turns out even). Im going to upload a pdf file of what i did already so i...
