METHOD FOR SYNCHRONIZING MULTI-CHP SYSTEM CLOCK SIGNAL USING RING OSCILLATOR AND APPATUS THEREOF

摘要

A ring oscillator is initiated. A ring oscillator according to the present invention includes: a receiver for receiving clock signals generated from a plurality of chips; And a connecting portion connecting each of a plurality of oscillator oscillators of the same fractal structure to each other with a corresponding end; And an output unit for outputting a signal oscillated by the oscillator of the same fractal structure; The oscillator can be set such that three nodes constitute one cell to have a fractal structure, an inverter is disposed between each node, and the clock signals are oscillated at the same frequency and same phase.
