Abstract(in English)	This paper demonstrates study on a feedforward active substrate noise canceling technique using a power supply di/dt detector. Our past study realized substrate noise canceling using a di/dt detector. For further substrate noise reduction, this study analyses the parameters which constitute a di/dt canceller and develops the effective di/dt noise canceling scheme. As a result, we realized 62% substrate noise reduction. Compared with effect of guard ring, our multiple di/dt canceller suppressed about five times as much substrate noise as that of guard ring.
