Abstract :
A new blind calibration scheme for M time-interleaved analogue-to-digital converters (ADCs), which models gain, time-skew and bandwidth mismatches as components of a transfer function mismatch, is proposed. Numerical results on the emerging generation of WiFI IEEE 802.11.ac with 12-bit ADCs show the effectiveness of the method.
