Design considerations for interleaved adcs

Webfour ADCs are interleaved. Note that there are three spurs in this example. A spur is a frequency component that does not belong in the output. It may or may not be a harmonic of the input frequency. Figure 3. Interleaved sampling of four ADCs, all with different phase errors Figure 4. Different offsets of interleaved ADCs will produce a spur ... WebAug 1, 2024 · By adopting several sub-ADCs in paralleling and recombining their outputs, a TIADC system can meet the high demand for sampling rate and resolution in communication system. However, the performance of a TIADC system is severely limited due to the channel mismatches among the sub-ADCs.
