ABSTRACT:
A system and method for controlling input buffer biasing current include an input buffer circuit with an input current detector circuit configured to generate a plurality of discrete biasing control signals. At least one input buffer is configured to adjust the biasing current in response to the plurality of discrete biasing control signals. The plurality of discrete biasing control signals is generated in response to variations in biasing current of the at least one input buffer. The method compares a representative bias current indicator from a replica of an input buffer with a reference current to determine variations in biasing current of at least one input buffer. A plurality of discrete biasing control signals is generated indicating a configuration of a biasing control for the at least one input buffer. The at least one input buffer is biased according to the plurality of discrete biasing control signals.
