Patent ID: 7525462

Claim:
A system comprising: a plurality of interleaved analog-to-digital converters, each associated with a corresponding conversion rate at which an input analog signal is converted to an output digital signal; a coarse programmable gain amplifier (PGA) controller configured to characterize the output digital signal of each of the analog-to-digital converters and to output a coarse gain control signal based thereon; a coarse programmable gain amplifier configured to receive the coarse gain control signal and configured to amplify the input analog signal based thereon and output an amplified signal; a splitter configured to divide the amplified signal into a plurality of amplified signals; a fine PGA controller configured to determine a fine gain adjustment for each of the plurality of interleaved analog-to-digital converters and configured to output a fine gain control signal for each of the corresponding plurality of analog-to-digital converters, based thereon; and a plurality of fine programmable gain amplifiers, each corresponding to one of the plurality of interleaved analog-to-digital converters, and each configured to receive one of the plurality of amplified signals and a fine gain control signal and output an individually-amplified signal to a corresponding one of the interleaved analog-to-digital converters.
