NMOS characteristics simulation in LTspice XVII
HTML-код
- Опубликовано: 5 фев 2025
- The following curves have been simulated in LTspice for NMOS:
1) Id v/s Vds for different values of Vgs
2) id v/s Vgs
Concept of model file has been explained and effect of varying the parameter VTO (Threshold voltage of NMOS) in model file can be studied on the characteristics of NMOS.
Madam amazing !! even in whole 2 hour class in my college i could not understand it and you cleared everything in 9 minutes I bow my head in appreciation!!
This video clearly displays why you are the gold medallist of banasthali university , the command on the intricacies of subject is another level
Amazing work! Totally saving my academic life rn !!!!! Thank you
Glad to know that ! 😇 please subscribe to my channel 😊
THANK YOU MAM FOR SUCH A CLEAR EXPLANATION.
good explaination keep posting more ltspice video
Hi!
Thanks for the appreciation! please subscribe to my channel to get notifications of the new videos.
Tremendoo!
Very Good explanation didi❤
Can you add subtitles? This is very helpful for people with poor English listening skills.
If do that, I believe that there will be more people can to see your teaching video. thank you very much.
Hi Joseph!
Thanks a lot for the suggestion. However, RUclips provides an option "CC" at the bottom right corner. You can click there and get the subtitles.
Hi Sanjeevni:
Thanks a lot, but I can't find the "CC" button in the right bottom corner of this video，because the CC(closed caption) button does not exist.
how to set W =250n and L=32n for PMOS? L is there in Model file but how to set W?
For that you have to select NMOS and PMOS instead of NMOS4 and PMOS4 from components. Then right click on the component and type the values of W and L.
What is the length of the channel you have used?
hello there i need some help in Ltspice for Op Amp and Nmos using .. can you
how to plot c-v curve nmos?
Hi teacher, If I use current probe to detect the Drain current(Id) whose value is positive in Id-VGS curve. If I use current probe to detect the Source current(Is) whose value is negative in Is-VGS curve. But the current has only one direction from Drain to Source, why one terminal is positive, and another terminal is negative ? thanks a lot.
Hi Joseph!
First of all there is nothing like positive or negative current. Actually, the basic thing is that the current flows in the direction opposite to that of the flow of electrons. When you apply Vgs>Vt and Vds voltage, then electrons flow from Source to Drain terminal through the channel created by Gate-to-source voltage Vgs. Hence, Id flows from Drain to source, which is named as drain current. Now if you talk about source current, it is nothing but a current opposite to the flow of drain current. Practically, no such current flows because current always flow in the direction opposite to that of electrons. Thus, theoretically, Is is negative and Id is positive.
Hope this helps!
Teacher, so "Id" current's definition is that the current flows from Drain to Source terminal. "Is" current's definition is that electrons flows from Source to Drain terminal. Excuse me, is my understanding is correct ? thanks a lot.
@@josephhuang6585 there is no current like Is. Only Id exists because of flow of electrons from source to drain. Is is just a theoretical concept. If you talk about Is, electrons should flow from Drain to source, just the opposite of the conditions for Id.
Thanks for sharing
thanks for help. can you do a video for DTMOS please.
how can i get model 3/54
Hi, how to simulate the nmos to check for the uncox? Thank you!
Hi! You can check the value of unCox from the model file of NMOS. UnCox is written as "KP" in the model file.
