Abstract- We discuss time-interleaved analog-to-digital converters,fsM o27= TI-ADC (ADCs)asa primeexampleofmerging analog anddigital signal processing. A time-interleaved ADC (TI-ADC) consists ofM parallel,ADC channel ADCsthatalternately takesamples fromtheinput signal, where l thesampling ratecanbeincreased bythenumberofchannels compared,f7|1Y/l= toasingle channel. We recall theadvantages oftimeinterleaving and,l investigate theproblems involved. Inparticular, we explain theerror analog input .
