Timing mismatch calibration for time- interleaved ADC

The project displays an all-digital background calibration for timing mismatch in time-interleaved analog-to-digital converter. Digital adaptive timing mismatch estimation and digital derivative based correction is combined to attain lower cost and better correction of timing mismatch. An expression for signal to noise and distortion ratio (SNDR) of four-channel after correction. Simulation result will show signal of various stages of the project (sampling by each ADC channels, the signal after derivative filter, timing mismatch estimator, and corrected signal). Results also confirm SNDR characteristic of vin, sampled and corrected signals.Bachelor of Engineering (Electrical and Electronic Engineering
