Abstract
Mismatches between the channels of timeinterleaved analog to digital converters (TI-ADCs) cause offset, gain and timing errors of which the timing errors are dominant
at high frequencies. The paper explains the mismatches and evaluates existing correction methods. This paper also proposes a background mode, mixed domain, calibration method for timing correction of TI-ADCs. The method improves the SFDR and SNDR of the TI-ADC for time-invariant and time-variant timing mismatches. A hardware demonstrator of the proposed method is realized with off-the-shelf components. The results of the demonstrator are compared with those of existing methods
