【目　录】:
Achieving the highest 0.1dB bandwidth flatness is important in many video
applications. Because of the critical relationship between the feedback resistor and
the bandwidth of a CFB op amp, optimum bandwidth flatness is highly dependent
on the feedback resistor value, the resistor parasitics, as well as the op amp package
and PCB parasitics. Figure 2.1 shows the fine scale (0.1dB/division) flatness plotted
versus the feedback resistance for the AD8001 in a non-inverting gain of 2. These
plots were made using the AD8001 evaluation board with surface mount resistors.
