PERFORMANCE vs. COMPONENT VALUES

The influence that each component has on the AD8099

frequency response can be seen in Figure 68 to Figure 73. In

Figure 68 to Figure 73, all component values are held constant,

except for the individual component shown, which is varied.

For example, in the RS performance plot (Figure 69), all

components are held constant except RS, which is varied from

0 Ω to 50 Ω. Figure 69 clearly indicates that RS has a major

influence on the peaking and the bandwidth of the AD8099.
