Title
Spectral shaping of timing mismatches in time-interleaved analog-to-digital converters
Abstract
We introduce spectral shaping of timing mismatches in time-interleaved analog-to-digital converters (TIADCs). We show how to reorder the channel ADC sequence in order to achieve spectral shaping and provide optimization criteria. We present a simple channel sorting algorithm, which significantly improves the signal-to-noise and distortion ratio (SINAD) and the spurious free dynamic range (SFDR) by applying a simple low-pass filter. The power consumption of the presented timing mismatch compensation method is very low compared to other methods and does not significantly scale with the number of channel ADCs. Furthermore, the compensation method does not depend on the absolute accuracy of the identified timing mismatches, which vastly relaxes the requirements on timing mismatch identification methods. I. INTRODUCTION A time-interleaved analog-to-digital converter (TIADC) consists of M parallel channel ADCs sampling with the sampling frequency Ω s M
