Some over-compensation appears to be needed for the desired overshoot characteristics. Instead of intersecting
the A
VOL
curve at 18 dB, 2 dB of over-compensation will be used, and the A
VOL
curve will be intersected at 20
dB. Using Equation 8 for 20 dB, or 10 V/V, the closest standard value of R
C
is 240Ω. The following two
waveforms show the new resistor value with C = 390 pF and 2.2 nF. Figure 49 shows the final compensation and
a very good response for the 1 MHz square wave.
