A structure of ADCs which combines fold-interpolation and pipeline is introduced, as well as corresponding digital calibration method. The simulation shows that the performances of the ADC after calibration are improved a lot. The SFDR achieves 62dB at a sampling rate of 800MHz, when the input analog signal is at 397MHz.
