WebMar 21, 2005 · To significantly increase the sampling rate of an analog-to-digital converter (ADC), a time-interleaved ADC system is a good option. The drawback of a time-interleaved ADC system is that the ADCs are not exactly identical due to errors in the manufacturing process. This means that time, gain, and offset mismatch errors are … 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.
