Noise reduction in integrated circuits and circuit assemblies |
摘要 |
The present invention encompasses techniques for reducing digital noise in integrated circuits and circuit assemblies, particularly dense mixed-signal integrated circuits, based upon shaping the noise from the digital circuit and concentrating it in a single, or a small number, of parts of the frequency spectrum. Generally, the presence of noise in the analog circuit is less important at certain frequencies, and therefore the spectral peak or peaks from the digital circuit can be carefully placed to result in little or no interference. As an example, a radio receiver might be designed such that the peaks of the digital noise lie between received channels, outside the band edges of each.
