Publication number: 20090261911Abstract: A multi-phase oscillator includes a plurality of ring oscillators (21) each having a plurality of output ports and each formed by connecting an odd number of inverters (20) in a ring, and a plurality of resistance elements (30) coupling the output ports between the plurality of ring oscillators (21) so that all of the plurality of ring oscillators (21) operate at an identical frequency while keeping a desired phase relationship. The number of the ring oscillators (21) is not limited to an odd number but may be an even number. The multi-phase oscillator changes the state of a succeeding node of a phase coupling to accord with the state of a preceding node of the phase coupling by using the resistance elements (30) as phase coupling devices. If resistors are used as the resistance elements (30), the phase output accuracy greatly improves and high frequency oscillation is possible.Type: ApplicationFiled: November 30, 2006Publication date: October 22, 2009Inventors: Seiji Watanabe, Takashi Oka, Tetsuo Arakawa

Publication number: 20090140818Abstract: This invention relates to a phase-locked loop circuit and a data reproduction apparatus, which can reduce a processing time that is required for initial adjustment in the data reproduction apparatus. In a digital data reproduction apparatus having two control functions, i.e., phase and duty adjustments for binarized data, the phase comparison with one edge is performed only at the phase adjustment by means of a phase-locked loop circuit 33 having an edge switching means 4 which controls the phase comparator 1. The phase comparator 1 inputs the binarized and a bit synchronous clock, and switches the output between a comparison result with one edge, i.e., a rising edge or a falling edge of binarized data, and a comparison result with both edges.Type: ApplicationFiled: January 30, 2009Publication date: June 4, 2009Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Shinichi Yamane, Seiji Watanabe
