MOSFET Characteristics using LTSpice

[@pradeepjn9477]

Best information brother, thank you 😘

[@BalamuruganParandhaman]

Thank you

[@prathamarya8755]

This is a very neat explanantion.

Something is happening to the dogs in the background, check on them lol. Informative video. Thank you.

[@DuyNhatN01]

can u explain why we chose that value for your res, is it random?

[@BalamuruganParandhaman]

We have to choose the resistance value based on the maximum drain current capability of the device. For plotting the characteristics for the learning purpose, a random value which limits the current within device range is sufficient

good video

[@vinayk531]

What is the value of vdd you chose sir?

[@BalamuruganParandhaman]

12V

[@vinayk531]

@@BalamuruganParandhaman sir, have we used vdd anywhere in the circuit ? ??

[@BalamuruganParandhaman]

@@vinayk531 yes. The source V2 is considered as Vdd

[@brunoheringer324]

I tried picking some mosfet of the LTspice library but the characteristics tests didn't worked as before, have you tried it? Thanks in advance.

[@BalamuruganParandhaman]

Different MOSFET has its own voltage or gate drive requirement. The characteristics will be identical but not the values of voltage and current. Here I used a low power MOSFET which can be driven from a small signal source

Thank u

[@Sundaryt]

how do you find out gm?

[@BalamuruganParandhaman]

@@Sundaryt it's calculated from the transfer characteristics. Find the slope of the curve in linear regio. gm=id/vgs

[@Sundaryt]

@BalamuruganParandhaman ohh thank you

[@dacademy7153]

Bro which source wiil be first source if I want to draw id vs vgs plot

[@BalamuruganParandhaman]

Vds

[@praveenjrs3608]

Bro how to draw Cg-Vg characteristics?
