Abstract
An oscillator, generating multiple phases of clock signals having a uniform phase difference with a high precision by a simple configuration, includes a plurality of NAND circuits NDto NDhaving the same number of input terminals connected in a ring. Eight NAND circuits are connected, and an output node of each NAND circuit is connected to an input node of each NAND circuit up to the NAND circuit connected exactly two places, that is, the number of input terminals' worth of places, ahead.
