1. A method for biasing an input buffer, comprising:
comparing a reference current with a representative bias current indicator as determined from a replica of the input buffer;
adjusting a bias current in the replica of the input buffer while comparing the reference current and the representative bias current indicator; and
biasing the input buffer equivalently with the replica of the input buffer when the difference between the reference current and the representative bias current indicator is minimized.
