Hi everyone here.
I have been doing electro-technique since 2012 , a european term used to describe electrical engineering globally.
Now in 2024 , i am looking for latest trending subjects in electrical engineering , especially in regions like :
europe/middle east/north africa/east-south asia...
Need alternate for oscillator with part number "SIT8008AI-82-33E-28.636360", couldn't find one.
Should be compatible with FFF (form, fit and function).
Also, it should be active and not obsolete part, it would be helpful if you can provide a link for it.
Thanks in advance.
The power button of the device was broken and the fuse was burned. So, I changed the fuse, and then I directly connected it over the switch. It can be turned on and there is sound, but I accidentally found that there seems to be a channel that is silent. I changed the input terminal, but it...
So I bought a 1986 Ford ranger that needed the body harness completely rebuilt . As I'm ripping out the old harness I noticed something that looks like a wire nut with about 6 wires inside of it. Has anyone seen anything like this? Was this Normal for fords back then ? Or was this the result of...
Hello,
I simulated the two multivibrator models in CMOS technology using the cadence tool. I was expecting the model 2 with Schmitt trigger(ST) will show robustness in PVT (Process Voltage temperature) analysis as compared to model 1 due to ST. But this was not the case both the Models shows the...
Hello,
I am designing a Schmitt trigger oscillator based on a CMOS NAND gate. The block diagram along with schematics and its results are attached for your reference. I am using the CADENCE tool with 0.35um technology.
Question: it can be seen in the result, the charging time of the capacitor...
For power supply engineers, we look at waveforms many times, including input waveforms, MOS switching waveforms, current waveforms, output diode waveforms, chip waveforms, and GS waveforms of MOS tubes. Let’s take the GS waveform of the switch as an example to talk about the GS waveform.
When...
Hello there,
Nice to meet you!My name is Dragos.And I am a beginner in electronic and electrical engineering.I want some advices from you.I want to learn simulation S.P.I.C.E., using Mcro-CAP 12, or any profesional program,and I want to know how to begin the process of learning.I want to know...
Hello,
I am building Solar Guitar™ prototype, an eco-friendly, self-sustained musical instrument solely powered by the Sun.
10-15 watt, 2 speaker guitar amplifier with preamp/reverb/chorus/delay/overdrive will be installed into the guitar’s body.
Looking for a creative specialist to build this...
In a tutorial about h parameters of a two port network I find the below snippet unable to grasp. According to KVL, the total voltage in a loop is the algebraic sum of the individual voltages. But why in this tutorial ( equation 1 in below image ) it's given so. It should be something like V1 =...
Hey all,
I am wondering if someone could assist me in a project I'm trying to do. I feel out of place because electronics are not my forte, I haven't really worked on them so this would be my first project. In other words I need help and in the words of Michael Scott from the office you'll...
AWR schematic uses 2x25 and 2x50 Transistors from .15um WIN PE15 process to design a LNA that operates in Ka-band. Can I use the same design for Ku band from Ka design? If yes, why can we use it? How can I change it to be a KU band (12-16Ghz)? I have attached the awr file if needed. I would like...
I provided a circuit which should discharge at a specific time. But this circuit is not working as an oscillator. How should I make circuit which will give me oscillation?
I am stuck with this project here. I was trying to make a voltage controlled current source which can generate 1A with 5V. I used a digaram of 741. But it didn't work. Is there anyone who can help me with showing me a circuit that can work? Thanks.
Hi,
I'm thinking of making a multi drill for wood drilling, that uses anywhere from 6 to 9 9V or 12V DC motors. These motors would be wired in parallel, with one battery source. I'd mount a drill chuck on each of the motors shafts for a drill bit. Now, I need a little bit of help from you. Do...
I was looking for an 1MHz oscillator for AM radio transmitter circuit. But I couldn't find one with the 4 pin crystal quartz oscillator. How to make an oscillator by myself with basic electronics materials? Any Circuit or ideas?

I love to repair and rework PCB's, so I hope I will get something new related to PCB's and other electronic things.;)
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, I can't find anything about what capacitor to supply to a circuit. And why to supply it to a circuit. If I e.g have a circuit with a battery and a led, the battey is 3.2v, and the led's forward voltage is 2v, and the current limit is 20mA to the led.
Oh, and what happens when a capacitor...
