Many of the problems that occur when transforming a design from the mythical world of textbooks and SPICE to the real world emanate from the non-ideal power supply. Real power supplies can cause noise ...

Decoupling capacitors have long been an important aspect of maintaining a clean power source for integrated circuits, but with noise caused by rising clock frequencies, multiple power domains, and ...

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...

Separating the power/ground connections used for the analog sections from those used for the digital areas will improve the isolation of the power supplies. Adding external/internal filtering should ...
