Digital Mismatch Correction for Bandpass Sampling Four-Channel Time-Interleaved ADCs in Direct-RF Sampling Receivers

摘要

Time-interleaving analog-to-digital converters (ADCs) decrease the required sampling rate for one ADC to achieve giga samples per second (GS/s) rates. The gain and timing mismatches among the ADCs generate aliasing signals, degrading the spurious-free dyn
