20120044004TRACK AND HOLD ARCHITECTURE WITH TUNABLE BANDWIDTH - To date, bandwidth mismatch within time-interleaved (TI) analog-to-digital converters (ADCs) has been largely ignored because compensation for bandwidth mismatch is performed by digital post-processing, namely finite impulse response filters.
