Abstract:
1. A multi-phase pulse generator, comprising: a first delay block including an even number of ring-coupled first unit blocks having a first negative delay property; and a second delay block including an even number of ring-coupled second unit blocks having a second negative delay property, wherein the number of the first unit blocks and the number of the second unit blocks are the same such that each first unit block is paired with one of the second unit blocks in one-to-one sharing, wherein an output signal of each of the first and second unit blocks of each pair is connected to each other forming an output node to which the output signal of each of the first and second unit blocks of each pair is a different level, and wherein each output node outputs a pulse signal generated by racing the different levels of output signals from the paired first and second unit blocks.
