Time-interleaved Analog-to-digital Converters for Digital Communications
Techniques to overcome the errors caused by the offset, gain, and sample-time mismatches among timeinterleaved analog-to-digital converters (ADCs) in highspeed digital communication systems are presented. The errors introduced by these mismatches are adaptively corrected using digital signal processing blocks. Sampletime errors are corrected by modifying the operation of the existing adaptive r...
متن کاملOn Blind Identification of Gain and Timing Mismatches in Time-Interleaved Analog-to-Digital Converters
Gain and timing mismatches in a time-interleaved analog-todigital converter (TI-ADC) cause spurious images in its output spectrum thus effecting its performance. In this paper. we present an efficient digital blind identification structure to adaptively estimate gain and timing mismatches by using the filtered-error least-mean square (FxLMS) algorithm. The identification of mismatches helps in ...
متن کاملA Calibration Method for Nonlinear Mismatches in M -Channel Time-Interleaved Analog-to-Digital Converters Based on Hadamard Sequences
Abstract: The time-interleaved analog-to-digital converter (TIADC) is an architecture used to achieve a high sampling rate and high dynamic performance. However, estimation and compensation methods are required to maintain the dynamic performance of the constituent analog-to-digital converters (ADCs) due to channel mismatches. This paper proposes a blind adaptive method to calibrate the nonline...
متن کاملCompensating Frequency Response Mismatches in Time Interleaved Analog to Digital Converters
Time interleaving of multiple analog-todigital converters by multiplexing the outputs of (for example) a pair of converters at a doubled sampling rate is by now a mature concept—first introduced by Black and Hodges in 1980. Time interleaving of ADCs offers a conceptually simple method for multiplying the sample rate of existing high-performing ADCs. Time-interleaved analog-to-digital converters...
