发明名称 SIMULTANEOUS SWITCHING NOISE CANCELLATION BY ADJUSTING REFERENCE VOLTAGE AND SAMPLING CLOCK PHASE
摘要 A data signal is transmitted from a first circuit to a second circuit, with noise and/or jitter added to the data signal by supply noise in the power distribution network in the first circuit and/or a second circuit being effectively canceled out by adjustment of the reference voltage and/or the phase of the sampling clock used for sampling of the data signal in a manner that effectively mimics such noise and/or jitter added to the data signal. The second circuit uses a filter that has the impedance profile and/or the jitter profile of such power distribution network. The bus weight and/or the number of switching bits in the data pattern transmitted from the first circuit to the second circuit is applied to the filter to determine the adjustment to be made to the reference voltage or the phase of the sampling clock.
