Figure 20. Frequency behaviour of the circuit of fig. 19
The system requires that DC gain is maximum to achieve good accuracy and line rejection. Beyond this
a bandwidth of some KHz is usually required for a good load transient response. The error amplifier trans-
fer function must guarantee the above constrainst. A compensation network that could be used is shown
in fig. 21.
