Abstract:
     A method and apparatus for an automatic gain control (AGC) loop that utilizes multiple comparators to provide constant bandwidth tracking and step response, as well as fine granularity for decision directed convergence. In one embodiment, an odd number of comparators is used with square-law scaling at the output to achieve constant bandwidth step response for a wide range of input amplitude changes.
