Digital Calibration for Gain, Time Skew, and Bandwidth Mismatch in Under-Sampling Time-Interleaved System

Digital Calibration for Gain, Time Skew, and Bandwidth Mismatch in Under-Sampling Time-Interleaved System

This paper presents an all-digital background calibration method for gain, time skew, and bandwidth mismatch in <i>M</i>-channel under-sampling time-interleaved analog-to-digital converters (TI-ADCs) systems. Firstly, the characteristics of offset, gain, time skew, and bandwidth mismatch...
