    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
