A 600MS/s 30mW 0.13µm CMOS ADC Array Achieving over 60dB SFDR with Adaptive Digital Equalization Time-interleaved ADC array –High sampling rate, low power –Channel mismatch errors Offset, gain, linearity and skew Approaches –Correlation, statistics, and Chopping Slow convergence, involved analog path, ad-hoc solutions –Equalization Fast convergence, digital post-processing, systematic solution

Equalization-Based Conversion Architecture Channel mismatch errors automatically eliminated w/ equalization !
