In either case, the capacitance CX causes the system to go from
a one-pole to a two-pole response; this additional pole increases
settling time by introducing peaking or ringing in the op amp’s
output. If the value of CX can be estimated with reasonable accu-
racy, Equation 2 can be used to choose the correct value for
a small capacitor, CL, which will optimize amplifier response. If
the value of CX is not known, CL should be a variable capacitor.
As an aid to the designer, the optimum value of CL for one spe-
cific amplifier connection can be determined from the graph of
Figure 41. This graph has been produced for the case where the
AD744 is connected as in Figures 39 and 40 with a practical
minimum value for CSTRAY of 2 pF and a total CX value of 7.5 pF.
The approximate value of CL can be determined for almost any
application by solving Equation 2. For example, the AD565/
AD744 circuit of Figure 34 constrains all the variables of Equa-
tion 2 (GN = 3.25, R = 10 k
, FO = 13 MHz, and CX = 32.5 pF)
Therefore, under these conditions, CL= 10.5 pF.
