[SOLVED] How to determine the Specific current of the MOS transistors in CADENCE

[muffassir]

Hi all,

How to determine the specific current of the nMOS /PMOS transistors.
Specific current is given by

Is=2nuCoxVt(square)W/L

which is used in the Ids equations of the MOS in strong and weak inversions.

I want to know the procedure to find the specific current in CADENCE VIRTUOSO 6.1.4

Any help is much appreciated...

Thanks

You should find µ , tox & Vt in your process specific SPICE model files, then calculate Cox from tox.
For n use values between 1.3 .. 1.5 , s. e.g. this output characteristic:


Binkley's book (cf. image above) gives reference values for all these values for different process technologies on pages 41-43 .

Hi Erikl Sir,

wow thts the book i needed the most..!!!

I got it from one of my sources and reading started also....

Thanks a lot for unconditional replies to the Posts...may *** keep you Long Live !!


Bye Tc.

 

[muffassir]

can anyone send me the spreadsheets of the author BINKLEY....I cannot download them from this page:

**broken link removed**

It gives me erorr when i fill all fields and click submit !!. Please download a set and then email me at muffassir@gmail.com

Or else if u own it then pass it to me ... Its Freeware..
