Power Supply Noise Reduction
by Ken Kundert
An introduction into the basics of power supply noise reduction using supply bypassing
and decoupling.
Introduction
Many of the problems that appear out of Murphy’s box upon 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 and spurious oscillations that can
force the designer into a frustrating glitch hunt. Rules of thumb can usually be applied
successfully to simple problems, but a little understanding and forethought will usually
provide clean solutions to even the more obscure problems. With this paper, I hope to
provide the understanding of some of the dynamics of power distribution. The forethought
is up to you. |
