  Time interleaved analog-to-digital conversion (TIADC) based on parallelism is
an effective way to meet the requirement of the ultra-fast waveform digitizer
beyond Gsps. Different methods to correct the mismatch errors among different
analog-to-digital conversion channels have been developed previously. To
overcome the speed limitation in hardware design and to implement the mismatch
correction algorithm in real time, this paper proposes a fully parallel
correction algorithm. A 12-bit 1-Gsps waveform digitizer with ENOB around 10.5
bit from 5 MHz to 200 MHz is implemented based on the real-time correction
algorithm.
