can anyone explain me in brief about why pinch off actually occurs? Is it because of recombination of the moving electrons from source to drain while the channel is open and the holes of the drain.
Pinch off occurs because of the increasing depletion region near drain due to increasing drain voltage Vds. Now since in depletion region there cant be any mobile charge thus there is pinchoff. Further if you go through Velocity saturation model it can be shown there is no pinchoff as the current saturates long before Vds(sat) due to velocity saturation especially in short channel devices.
Sir, if I apply Vg>Vt and after that leave the gate open, will I be able to conduct current forever between drain and source or will the channel decay off. Pls help me with this
After watching hundreds of vedio on mosfet i must say your lecture is just outstanding
Lectures are good sir, We are getting the concepts present in the MOSFET. Thank you.
🙏🙏
Some lectures including this, are not showing in the edc playlist..
Enlightening Excellent Session

where can i get this ppt?
You have to visit to the nptel official sites and find course there you will have transcript option go for it you will all notes there
