Abstract:
1. A system comprising: a first amplifier stage having an input and an output, including a first gain-tilt amplifier having programmable tilt compensation; a second amplifier stage coupled between the output of the first amplifier stage and a first output node, the second amplifier stage including a second gain-tilt amplifier having programmable tilt compensation, and a third gain-tilt amplifier having programmable tilt compensation; a loop-through amplifier coupled between the input of the first amplifier stage and a second output node; and a gain profile controller, coupled to the first, second, and third gain-tilt amplifiers, configured to independently control the tilt compensation of the first, second, and third tilt-gain amplifiers; wherein the first tilt-gain amplifier is configured to apply a coarse tilt compensation and the second tilt-gain amplifier is configured to apply a fine tilt compensation.
