Abstract :
Gain errors and offsets in time-interleaved structure A/D converters result in distortion in the output spectrum. To reduce these effects, a new method utilizing randomization technique is proposed. Simulation results show that the distortion level caused by gain errors and offsets was lowered. One of the advantages of this proposed method is that it requires low hardware cost to implement when compared to other auto-calibrating methods
