A new DFT based approach for gain mismatch detection and correction in time-interleaved ADCs


This report introduces a new approach for detection and correction of gain mismatch between ADC sub-channels in time- interleaved ADCs. Based on discrete Fourier transform, this technique uses a simple approach for gain mismatch correction. MATLAB simulation results are represented for correction of ±2% gain mismatch in a two-channel time-interleaved… (More)
