mosfet

Dear all, can anyone share TL072 op-amp LT Spice Model with me (probably better if placed in zip file ) ? I am trying to simulate a TL072 to produce 1MegaHertz sine wave :) Thank you for your help :)

Below is Triangular Modulation Output of a Triangle input wave HI all, I have been trying to understand modulation and demodulation circuitry as part of my hobby :) The modulation circuit above works fine but when I connect the output of the modulator to the demodulator (as shown by blue...

I am wondering if it would be possible to swap out the MOSFETs on the picoUPS-100 by Mini-Box for higher-powered ICs. I know it would void the warranty, but it would be great to get a little more juice out of the device...

Referring to website link at here , this circuit tries to replicate the waveform of input voltage and make it to a high frequency, I try to simulate the circuit in LT Spice but the output is weird. May I know the solution to this? Below is my attached LT Spice for your convenience. Thank you...

Both of this graph show mosfet and but in switching mode As i look at the graph below I notice for mosfet the drain source amplitude is higher than the gate voltage amplitude . However , bjt , collector voltage amplitude is only reach at the same amplitude of base voltage amplitude. From this...

I'm looking to use an optocoupler+MOSFET to switch "undefined" DC power sources; the opto I'm looking at is FOD817D and the MOSFET is FDPF55N06. The power sources may range from 5V (USB power) to 24V, but I could see this being used to switch as high as 36V at some point in the future, and...

Dear all, I am looking for a circuit that can on an led by pressing the same button for 3 times? Thank you for reading and have a nice day:)

Hi all, I'm trying to drive a RFP30N06LE N-Channel MOSFET with TC4420 MOSFET Driver. The MOSFET is used to switch a [1W LED][1]. The input to the MOSFET driver is provided by the 5V from an Arduino Nano. But my circuit is not working: it seems that the VDD somehow leaks to the input of the...

Hello Hello I am using a MOSFET driver circuit with SI2303 as p-channel mosfet and SI2302 as n-channel mosfet. I have given control signal (of 5V) on the gate of n-channel mosfet to turn-on and off the p-channel mosfet. However, the p-channel mosfet is not getting off and I am constantly...

I'm working on a remote start system for an older gm diesel vehicle and so far everything has worked great, but I've hit a stump that I just cant figure out. The engineers who designed the ignition switch of my truck though it would be a good idea to run starter solenoid power though the...

Hello, I have a question regarding operational amplifiers. Whenever I search for some datasheets of high gain and high-speed Op Amps ( BW higher than 50MHz), I mostly find that they are made of bipolar transistors rather than mosfet. Why is it so? I've done some research and I've found that...

Hello, I have a dumb question about the working principle of a normal mosfet. When it is used as a switch, when we apply a gate voltage higher than the threshold it will output the voltage present at the source. It happens because it is working on its linear region. When we use a mosfet in a...

I using the MOSFET IRFB3004PBF switching. 56.2V is a source voltage coming from the charger and 48 is the nominal voltage of the batter. switch S1 is for switching Vgs. Vgs=5 v. Rgs=10k ohms (connected to the gate terminal and battery ground). battery is 13s3p Nominal=48v Peak=54.6v Will MOSFET...

Hello everyone. I am working on a project that involves the use of MOSFETs to turn a matrix of electromagnets on/off. The project is quite complex and involves several different circuits, but for facilitating this specific discussion, I have simplified the circuit to focus on this specific...

The other day I got the following exercise on one of my exams: For those who don't speak German, for transistor 1 lambda is 0, but not for the others. The backgate-effekt should be neglected alltogether. I drew the following small signal equivalent circuit (ignore the black texts for now)...

I want to buy a MOSFET in the rating of 600V/20A. I also want to buy MOSFET driver for that. I have to use it with Arduino Uno for controlling purpose. But I can't select which one to buy. Can anyone suggest me a good MOSFET + MOSFET Driver?

Hi all, I refer to this website at here . This circuit should give a complementary square waveform (R1 square wave & R2 inverted square wave). However, I did get a good square wave across R2 but R1 did not get any square wave. Does anyone know how to fix this? I have attached my LT spice below...

Hi all, I bought this IR 2184 which is used in half-bridge inverter. Will the peak voltage of PWM of GS of mosfet as shown in green will be according to Vcc which means in this case, if I use a Vcc (12V) and PWM of 8V peak (IN), it will output a 12V peak square wave at GS of both mosfet? And...

Hello guys New here. I am trying to work out what would be the best way to control a 2v load using something like an ESP32 (3.3v) So what i have is: ------------- | BATTERY | (1.5 - 2.2v) ---> something?? >>> Resistor ---------------...

I am experimenting with an inductor to see what is happening when it gets saturated and at which current it happens. So I set up the attached test circuit and checked the current on the 1Ω resistor. I expected the current to ramp up until the inductor gets saturated and then to increase at even...
