ABSTRACT:
A time-interleaved analog-to-digital converter (ADC) is provided. The ADC generally comprises a first ADC, a second ADC, correction circuit, a divider, and a clocking circuit. The first ADC receives an analog input signal and generates a first output and a differentiated output. The second ADC receives the analog input signal and generates a second output. The correction circuit receives the first output, the second output, and the differentiated output and generates a first error signal and a second error signal. The divider receives the first error signal and the second error signal and generates a timing error by dividing the second error signal by the first error signal, and the clocking circuit receives a clock signal and the timing error and generates a plurality of corrected clocking signals, where each of the first and second ADCs receives at least one of the clocking signals.
