Closed-Loop Gain vs. Frequency for the Circuit of Figure 29 Figure 32 is an oscilloscope photo of the pulse response of a unity gain inverter which has been configured to provide a small signal bandwidth of 53 MHz and a subsequent slew rate of 180 V/ µs; resistor R F = 3 k Ω, capacitor C COMP = 1 pF. Figure 33 shows the excellent pulse response as a unity gain inverter, this time using component values of: RF = 1 k Ω and CCOMP = 4 pF. Figures 34 and 35 show the closed-loop frequency response of the AD829 for different closed-loop gains and for different supply voltages. If a noninverting amplifier configuration using current feedback compensation is desired, the circuit of Figure 36 is recom- mended. This circuit doubles the slew rate compared to the shunt compensated noninverting amplifier of Figure 27 at the expense of gain flatness. Nonetheless, this circuit delivers 95 MHz bandwidth with ±1 dB flatness into a back terminated cable, with a differential gain error of only 0.01%, and a differential phase error of only 0.015 ° at 4.43 MHz.
