Optimum Feedback Resistor
Although a current feedback amplifier’s bandwidth
dependency on closed loop gain isn’t as severe as that of a
voltage feedback amplifier, there can be an appreciable
decrease in bandwidth at higher gains. This decrease may
be minimized by taking advantage of the current feedback
amplifier’s unique relationship between bandwidth and R
All current feedback amplifiers require a feedback resistor,
even for unity gain applications, and R
the internal compensation capacitor, sets the dominant pole
of the frequency response. Thus, the amplifier’s bandwidth is
inversely proportional to R
optimized for a 250Ω R
decreases stability, resulting in excessive peaking and
overshoot (Note: Capacitive feedback will cause the same
