MOSFETs are the most commonly used devices now-a-days.
Let's see how MATLAB can be used to study the code and working of
an n-channel MOSFET
n-channel enhancement type MOSFET
I have a code given in my blog. You can use the same code and you can do
your own
uh... editing.
Open the MATLAB software
and click file and click open. I have written the code already. So, I am opening it from here.
It's named as early. If you are doing it for the first time
click file and new and blank file and copy
uh... and copy the code from my blog
and click paste here.
It gets pasted here.
At the bottom of the window you can see
whatever m files you have opened.
So, I am going to 'earlier' right now.
Now, this is the code I have given in my blog. I have
uh...done some editing as well.
This is the code for an n-channel enhancement mode MOSFET output characteristics which gives the output characteristics of the device.
This is a % sign used to add comments in between the MATLAB
code.
'Clear all' clears all the unwanted things already there in the command window.
The equation for the
MOSFET as you know is
uh...
has the constants like 'mu en *** W/L'
It's an important parameter.
and that is written as
'mu en ***'
is equal to kn
uh... and that's taken as 100 micro amperes. Usually this's the
range of values that you would expect for
this constant. Here it is 100 micro ampere per volts.
You can even customize this by
uh... asking the users to input
uh... what value..what code do you want,like, I will talk about it
well
later.
Now, W/L is a very important parameter that gives the ratio of the width to length of
transistor. I have taken it as 2.
here.
uh...since uh... one eighty nanometer technology is the most common
most recent
technology being used
uh... by most of the outstanding companies in the field
like INTEL, TSMC. They have 180nm technology. So, I am also sticking to the same.
In 180nm technology, the value of lambda is 90nm.
uh...
and that of
so therefore the length will be
length of the channel will be
as per design rules has to be 2 lambda. So I am choosing 180nm here.
That is 2 into 2 lambda. W is taken as 4 lambda, that is usually what we do.
for a minimum size transistor will be usually 4 lambda by 2 lambda in size.
it's not that W=L for a minimum size transistor, that's not true.
Usually, it's 4 lambda by 2 lambda for a minimum size transistor.
Now beta is the product of k into W by L
So, that's what you see in this code.
