Hi

I need a brief explanation on how a Current Mirror is used to Bias an NMOS using Constant Current Model. My Doubts are :-
* Where the input is given ?
* If the current remains constant how does it work ?
* If the current does not remain constant then why say constant current ?
Bit Confused. Little help needed. :)

Thanks
Salil
