Multi-process a/d converter in which output synchronization among the processes is corrected

The present invention relates to a multi-process A / D converter, by feeding back the output of the each path and detects the phase to generate a delayed clock signal having a different delay time in accordance with the phase difference, each of the paths using the delayed clock signal, and an output wherein the correction. According to the multiple A / D converter according to the invention, delayed by the signal by using the clock signal, and correct the error itself generated in synchronization with the clock signal it is possible to reduce the distortion of the signal to correct the output of each path.
