Impact of random channel mismatch on the SNR and SFDR of time-interleaved ADCs
(Institute of Electrical and Electronics Engineers, 2004)
Using several ADCs (Analog to Digital Converters) in parallel with convenient time offsets is considered as an efficient way to push the speed limits of data acquisition systems. However, a serious drawback of this ...
