Abstract

Generally, noise is reduced through an effective use of de-coupling capacitors, and their effectiveness is a function of the value of the capacitance, the series inductance and the series resistance. Noise is reduced by increasing capacitance and/or by decreasing inductance and/or by decreasing resistance. This noise, in its simplest terms, is represented by the equation: Vnoise = Leff x dieff/dt
